A Documentary Review of PBS: America’s War on Poverty

The Public Broadcasting Service takes on the War Against Poverty, President Lyndon B. Johnson’s brainchild in a television series. The series shows how poverty touches the entire American political and economic system. As racial divides are thickly drawn with a black marker, a massive redistribution of wealth is found to be necessary. This is in contrast to the prosperity victory in World War II brought to the United States.

The director uses political footage, interviews from authors, citizens, and politicians alike to show the dramatic widespread effect of poverty, as well as the machinations that made change possible and the vehicles for effecting that change in operation. Combining black and white footage, with modern colour film drives home that this film is part of American history, as much as it is the present. Sadly, the American history of poverty, and Native American struggles are ignored. Racial divides are not absent, but are set aside to the second half of the film, as the film has a dialectic focus on the Equal Employment Opportunity Act and the Civil Rights Act. However, this is appropriate because the War Against Poverty is a specific time-place referring to the 1960’s, though those unacquainted with this, will be confused by the title and content.

“The very things that made America great its inventions… were causing some Americans to be left behind.” The joint continuous miner brought the story of John Henry, in which a man labours to death against a machine, to reality on a societal level. Coal miners found steady work and good wages evaporating to the hypnotizing diligence of the mechanical workers.

By 1960 nearly half of residents in some counties in coal-mining Virginia relied on government aid. In the words of John F. Kennedy, “automation did it.” An exodus of former coal miners seeking work and african-americans fleeing racism arrived in the North and changed the country. In the capital as well, a march on Washington signalled a substantive movement towards change in the country. Poverty was geographical, and with the help of unions and politicians like Kennedy, racial lines became shattered.

Violence broke out. Homes and bridges were bombed. A decade before the race riots became bloody, and years before the Vietnam war, destitution was driving Americans to fight for their right to live, or death by starvation. Before the political promises of Kennedy could be carried out, he was assassinated. Carrying out his promises was a medical necessity. In states such as Mississippi, poverty and lack of healthcare caused parasites, lethargy, and severe anemia in children. Nowhere was poverty greater.

But all was not lost. There was no initial confidence in Lyndon B. Johnson, but using a variety of political and legislative means, he was able to “continue” both domestically and abroad, the goals of the administration and American people. The African-American movement was growing in the public conscious, but the backlash against it would have killed what chances there were had it not been for Head Start and the Civil Rights Act of 1964. By ensuring the poor could vote, and that race did not factor into this, the end of segregation was in sight. More importantly, this minority, which had a lower population growth than the Jewish population in Germany due to economic impoverishment, was given opportunity to become full partners in the make-up of this nation.

Surviving the depression, Johnson made significant inroads to Americans, enacting the first anti-poverty legislation since the Great Depression giving needed alleviation to Americans, to “replace their despair with opportunity.” He created a task force, and began a movement to change the country. In some states, it was a matter of saving lives. The idea that black Mississippians could control anything was considered to be ludicrous, and this was seen in their oppression, and reversed by their first true liberation, with economic and political equality. Before they could lose their job, their welfare when they voted.

Sargent Shriver was appointed head of the War Against Poverty, and with what some would call blind optimism, energetically took on the job. He had expertise setting up the Peace Corp, and was able to use this domestically with efficiency. Unable to levy higher taxes, and without a comprehensive job program the questions existing are problematic. Investigating voting problems made enemies, but it was a political sacrifice that had to be made. As workers protested discrimination and were incarcerated, the CDGP made allocations of federal money to post bail for these workers under the auspices of work salary advances.

The mixing of the Civil Rights movement with the War Against Poverty created humiliation for Shriver, and was seized upon. Yet these were two movements intertwined, and impossible to separate. As the opposition insisted “don’t you ever give up that gun, that is all you’ve got to protect that little baby in that crib” the documentary shows the backlash was not one which could be stood up against without great courage. Klansmen were marching unhooded and unafraid of retribution, despite their violent message, and African-American protestors needed the same protection, though without the threat of violence.

As planes began to fly in the South Asian peninsula, Johnson signed the Equal Employment Opportunity Bill into law. Suddenly the education programs and hand-up (not hand out) the federal government had offered America’s poor looked smart; the country was going to send a conscript army into war. Racial equality would also figure in importantly towards preventing this war from tearing the nation apart at the seams. This would seem to be an appropriate direction for the documentary, but for better or for worse the film begins discussion in the last section of reorganization and scandal in anti-poverty movements.

Apocalypse Now: Horrors of a Heart of Darkness

Apocalypse Now: Horrors of a Heart of Darkness

Apocalypse Now opens to destruction in the jungle of Vietnam, as Jim Morrison’s smooth definitive psychedelic rock song The End plays, a Captain Willard’s smoking head and torso are superimposed, letters are strewn on the nightstand, but sleeping now the soldier has disappeared into a haze of smoke and Cordon Bleu. The soft beating of a helicopter transitions to the fan in a squalid apartment with cheap blinds..

“Saigon. Shit.” This soldier dreams of the jungle, of returning to the pain he left behind. Director Francis Coppola is put in a dirty place between anti-war sentiment that can guarantee this film popularity, and the squelching  necessity to portray the US Army in a positive light. He does neither. But this is done brilliantly. The story is based on Heart of Darkness, and the struggle to find God in war is one that resonates with the violence and prejudice of that novel. Yet the mission is not to carry out this violence, but to stem the violence. In a special operations assignment a bloodthirsty American colonel must be terminated. The captain is accustomed to death, “but this time, it was an American, and an officer.”

The target, Kurtz, represents an American dream, and this is used to bring the film home to every American. Regardless of whether they are accomplished or flunky hippies, everyone has had a moment of desire to be this man. Watching the betrayal of the American dream is as captivating as it is intriguing.  The absurdity of an expensive flame-throwing tank being utilized against a village is emblematic of the entire war for American viewers. A bombed church shows the destruction of values too many Americans identify with themselves.

The war was presented as finished, won. Yet the soldiers cannot leave their boat. The countryside crawls with Vietcong. Even on the patrol boat, riverside attacks occur, and the soldiers are helpless, inadequate or improper firearms and little shielding give them virtually no choice but to simply speed onwards, deeper, losing a crew member in the process. Suspicion is a dominant theme in this film, a paranoia looms large. Deeper in the jungle, the remnants of a post-apocalyptic war machine lie in ruin. Yet apocalypse in a temporal or legitimate sense cannot come quickly enough for the soldiers.

By showing a soldier burning alive, as chopper machine guns mow down villagers, the film depicts the horror of war. It is hard to believe that these are the same that were just shortly before seventeen year old surfers. Captain Willard cannot imagine how Colonel Kurtz can be fighting a worse war than that already sanctioned by the US Military. Soldiers and officers alike consider the Vietnamese to be natives, with only nominal respect shown for the dead and wounded. Then the Captain executes an innocent civilian. The viewer is in shock. Good and bad are wrenched in the same way the American at home was betrayed with the announcement of My Lai and illegal incursions into Cambodia.

As the war had been a sick carnival, the soundtrack and cinematography collide corrosively. Soldiers smoke marijuana, officers drink. tripping on acid, they are welcomed to the “asshole of the world.” As they arrive to the colonel, the barbarity of the actions of the soldiers he defends with the barbarity of the land he has come to. Seeing the heart of Cambodia, corrupted like this golden child of America, who now sees violence as a genius, the viewer is brought into the heart of darkness. The apocalypse now written on Kurtz’s temple is a call to arms, but one that the viewer will never answer. The jungle and quiet crickets isolate the evil completely. We can only look on with horror.

The end of the river comes as the end of the war. Awaiting an airstrike, the Captain confronts this mad, evil genius. “It smelled like slow death” and in the center, was this man’s lair. Without a timeline the entire film, urgency suddenly becomes paramount. Complete the mission and return to the boat by 2200 hours, or everyone will become engulfed in the flames of napalm. The Colonel’s slow words betray this urgency, his psychopathic nature, already aware of the Captain’s intent to terminate his command.

“He dies when it dies,” the words of the Colonel’s brainwashed civilian photojournalist indicate the paralysis and uselessness of the situation. A prisoner now, the Captain wakes up with the head of a soldier in his lap. He breaks down into tears. The Colonel lullabies him with read poetry. With the behavioural instincts and natural barbarity of a cat, Colonel Kurtz eats raw garlic as he quotes Heart of Darkness, “I’ve seen horrors, horrors you have never seen… you have no right to judge me.” He has been gripped by the barbarity of the villagers and war alike. As the film begins, it ends, Jim Morrison sings, and the Captain mows Kurtz down with savage justice, in war paint his machete against the red of fire like the sword of Gabriel. The Colonel’s last words: “The horror. The horror.”

Lung Cancer and Smoking in the UK

Britain has half the man-made and natural radiation combined as the US has just man-made.

http://news.bbc.co.uk/2/hi/uk/4709394.stm

Females and males stopped smoking in the same rates, from 41% and 52% to 23% and 25% (respectively).

http://www.cancerresearchuk.org/prod_consump/groups/cr_common/@nre/@sta/documents/image/mort_asr_uk_lung_png.png

Lung cancer mortality rates have remained the same (55 to 45 per 100,000), and actually increased for women (17 to 30 per 100,000). 

Confounding research on Chronic Inhalation Exposure to Mainstream Cigarette Smoke Increases Lung and Nasal Tumor Incidence in Rats - Human consumption of tobacco lowers lung lesions, tumours, and other malignancies

There are a number of procedural errors in this study which will be addressed as follows. Firstly the bias or affiliation of the study, published by Oxford University, is listed as pfizer, a corporation that makes smoking substitution products, and was caught bribing academics (in unlisted affiliations) with the intent of maintaining marijuana prohibition. Furthermore, the study was conducted in New Mexico, a part of the USA with high atmospheric radiation at this time, the non-smoking control received filtered air, while smoking groups were exposed to non-filtered air. The study asserts that in mice testing, supporting data was gathered that cigarettes cause pulmonary damage. 
The mice are divided into a control group, a "low-smoking" and a "high-smoking" group. The low-smoking group was exposed to the equivalent of between 20-30 cigarettes smoked continuously for six hours without stopping. The high-smoking group was exposed to the equivalent of 60-80 cigarettes per day continuously over a period of six hours and should have been disregarded as non-evident of human consumption patterns at any time in history. For the purposes of reality, the low-smokers (which in humans is at levels classified as heavy cigarette use), will be used in this evaluation. In addition, in this study the high smoking rats were starved (food consumption 60% of non-smokers), which also indicates this data is not reliable.
Despite the conclusion and abstract's assertion, the data is actually quite positive for regular smokers. Incidence rates of neoplasia in the nasal cavity was lower for smokers than non-smokers.  The survival rate for smoking rats is higher by a significant amount, from 752 days to 779 days. Lung weight of smoking rats was the same as non-smoking rats (an increase was seen by 60 cigarettes per day). Ciliated cuboidal cell metaplasia (mucus in the lungs, a deformity frequently observed with aging that has not been definitively connected to cancer, except in epidermal cases, and then only correlatively) was noted in a small amount in smoking rats. Squamous metaplasia was not observed in smoking rats, but were noted in the 60 cigarette per day group. Keratinizing squamous cysts were not observed in smoking rats, but were noted rarely at 60 cigarettes per day. There were no consistent trends in lung lesions, with sometimes lowest levels in the group smoking 60 cigarettes per day (eg. hyperplasia), sometimes lower in smoking rats (eg. malignant neoplasia) and other times in non-smoking (eg. benign neoplasia), though it should be noted this occurred in non-significant levels in all rats. There is no increase in nasal neoplasia for smoking rats. 
After all this, the study asserts that cigarettes are the cause of problems, but admits, "The reason this study produced significant increases in lung tumors in rats while previous studies did not cannot be determined with certainty." It is fairly clear that while, previous studies have linked regular human consumption to health benefits, the concept of gassing rats with 60 cigarettes per day had simply not occurred. See previous articles for data on cancer mortality rates in the USA and the probability that tobacco use in humans has numerous health benefits. While there is not data here on radiation exposure necessary to lower white blood cells in a rat, it is safe to assume these fall along similar lines with humans, and exposure to an unmeasured number of mrems of radiation was a significant factor in the development of malignancies in the rats. It is possible that filtered air might make a difference in mucous accumulation in rats as well as humans, though this is not definitively connected with cancer or malignant symptoms.

Increasing cancer mortality rates despite technological advances and drastically lower tobacco use in the USA: 1950-2015, 65 years of cancer theory down the drain?

There is no explanation for why cancer mortality rates have not gone down (and have gone up) despite medical advances as the entire nation has stopped smoking. Investment in screening and treatment can ensure near 100% recovery, yet all budgeting goes to cheaper "prevention" which does not work. Since the US cracked down on tobacco use, with success in white males, the overall cancer mortality rate has increased from 184 per 100,000 in 1950-69 to 209 per 100,000 from 1970-1994. Today that rate holds steady at 203 per 100,000. In white females and in other demographics cancer mortality rates have been steady or changed in negligible amounts, but these demographics have had increasing tobacco use rates. Cancer is a painful and unnatural death that can often involve long battles with the disease and should be combatted with all resources available, in treatment and in prevention. While lung cancer rates have fallen, technological advances have allowed earlier detection of lung cancer, which at stages 0 and 1 is among the least deadly forms of cancer, but at later stages is among the most deadly. Without adjustments for technological advances in medical care, no positive statement can be made in regards to success or negative results from anti-smoking campaigns. Meta-data from overall cancer mortality does show that the resources in the war on cancer have been squandered and had an overall detrimental effect on the national health of the country, and some policy change is necessitated, although it must be noted there is no current biological explanation for the lower cancer rates in countries and places with higher tobacco use, these have been correlative not causal links. Atmospheric nuclear weapons testing does match up with the population data, it was ended by the 1970's with the Limited Test Ban, and in the continental USA in 1962, and there is solid science that shows inhaled radioactive particles cause lung and other cancer for 30-60 years after detonation.


See cancer rates in USA: http://ratecalc.cancer.gov/ratecalc/archivedatlas/pdfs/maps/acc-maps.pdf

It can also be noted that the demographic distribution provided in the atlas is vitally important as the female population increased smoking rates slightly and saw a slight decrease in cancer mortality as well as an increase in life expectancy commensurate with the increases seen before anti-smoking campaigns.



Please note that the modern terminology for measuring radiation exposure is the gray which measures radioactive exposure per kilogram of tissue, as opposed to the rad which was formerly used and is an absolute amount of radioactive exposure. In humans, one gray is equal to about 100 rads.

Study Estimating Thyroid Doses of I-131 Received by Americans From Nevada Atmospheric Nuclear Bomb Test, National Cancer Institute (1997)
Annual dose in rads

It can be seen above that the white and light blue areas of dangerous levels of radiation (previously believed that 2 rads annually were safe, now it is known that virtually no level of radioactive exposure is safe) matches smoking data exactly (as shown below, and later in the article). Cancer mortality on the other hand, has changed drastically as far as geographic distribution over the years. According to research done on rats, lung cancer can be induced in significant amounts with any amount of radiation, and differences between groups exposed to 1 gray of radiation (100 rads) can be seen to be at least 13 times greater than in control groups (LaFuma et al.).

According to mapping of fallout from nuclear weapon's testing the majority of the southern states in the USA are exposed annually to an average of over 1 rad of radiation, from fallout alone, exposure to this level of radiation (lifetime of around 100 rads) radiation results in a, "decrease in the circulating white cells and platelets." This results in a statistically significant increase in cancer in keeping with the findings shown on this atlas as, "The Biologic Effects of Ionizing Radiation report (BEIR V) states that if 100,000 people are exposed to 10 rads of radiation, then there will be 800 additional cancers in that population above the normally occurring amount."   Source: http://cancernews.com/data/Article/264.asp#sthash.qEIXcULD.dpuf

We can expect cancer rates to drop significantly as the average radiation exposure in the USA has dropped since this map was made in 1997, the current average annual exposure is still .6 rads per year, enough that there are a significant number of people with lifetime exposure exceeding 100 rads.

Finally, a primary concern of smoking (though the claim asserted by anti-smoking campaigns is that it increases all forms of cancer), has been lung cancer. This disease takes on average 20-30 years to develop (Howlander et al.), and while cigarette consumption had reached 80% and 90% of its peak by 1945 and 1950, respectively, lung cancer peaked in 1991 and 80% and 90% were reached in 1973 and 1980, respectively. Most importantly there are no spikes and dips as with tobacco use rates and consumption, but lung cancer is a smooth increase and decline, in direct communication with radioactive exposure and pursuant half-lives. Lung cancer mortality has not decreased in kind with decreasing smoking rates however, and in fact only plateaus with the ban of nuclear weapon's testing and nuclear power plant construction. While cigarette smoking has dropped by over half since 1975, lung cancer mortality has gone from 75 to 65 per 100,000, an insignificant change which after adjusting for atmospheric radiation actually indicates that smoking cessation has cost many lives.  See image below for lung cancer mortality in the USA.

A doctor I interviewed on this matter mentioned to me that it was a possibility that infectious diseases were accountable for the increase in cancer mortality, but that they did not know for certain, not having looked these statistics up. I have acquired the infectious disease mortality rate, and it has not changed since anti-smoking campaigns went into effect and in fact increased which means that the potential positive effects of tobacco may be even greater than suggested by simply looking at other raw data, possibly due to lost funding diverted to misguided anti-smoking campaigns. In any case the veracity of the failure of anti-smoking campaigns cannot be questioned in the war on cancer, and is a monumental public policy choice that must be reverted immediately.

Letter to Patrick Kennedy regarding conversation at Smart Approaches to Marijuana

Hello,
Regarding our conversation at the SAM conference this summer: I was lucky to have qualified my statements with illegal and decriminalized marijuana in relation to my research. I did indicate that further results from fully legalized areas and places of further research were being waited on. Since the conversation, the confounding factor of the toxoplasmosis gondii being extant in many marijuana smokers in places with home grow operations has forced a reconsideration of the numbers and statistics available. This parasite is responsible for the perceived negative impact of marijuana in countries that fail to complete proper legal research in keeping with UN treaties in effect currently. In Canadian and other studies have conclusively shown with virtually no room for error that marijuana use is associated with a 5 point increase in IQ in current smokers and 3.5 points in former smokers. This translates to literally trillions of dollars in lost intellectual property as can be seen in Germany where marijuana use among 18-24 year olds has quadrupled to nearly 28% while the economy has ballooned to nearly the same size as the United States while alcohol use has dropped dramatically. In MRI and SPECT scans the positive effect of marijuana when disambiguated from those infected with the common parasite, along with pesticides or other factors including income, has been concretely shown in Dallas and other university academic studies. There is some research to indicate that a compound from marijuana may mitigate the effects of alcohol, but this research is still in its infancy, at this time in the 45% of America that drinks, it can be associated with a drop in IQ of several points in comparison to a non-user, and many points in comparison with marijuana users. For the time being, this is a national security crisis in which every year 150,000 people are needlessly dying from alcohol related deaths. To put this in perspective, this is more than all military deaths in all American wars since the Korean war combined, every year. Furthermore we are unable to compete on a global scale as other nations, including Germany, with smaller populations are able to perform on a higher level than the United States. An increase of 5 points in IQ translates to 100's of % more geniuses and double the number of highly gifted in the population. We have made significant progress with industrial hemp legalization, which increases CO2 consumption by 4X that of other plants and can potentially offset global warming while increasing our energy independence. It is time to take these gains to other fields as well.
Legally, prosecution of marijuana is unconstitutional and the way it is currently implemented it is in violation of multiple UN treaties. According to our constitution, the supremacy clause in article 6 section ii only takes effect under certain circumstances. The most significant example of this was in the Civil War, when Abraham Lincoln was forced to issue an executive order freeing the slaves before legislation from the federal government could make slavery illegal. Unless it could be argued that marijuana prohibition is more important to national security than 600,000 legal racially defined slaves, this clause should not override pre-existing and later passed state laws in this matter. This has been defended and ratified in multiple state supreme courts in the case of marijuana. Furthermore, in the federal statutes there is a contradiction in the case of marijuana, making prosecution unfeasible and illegal by federal organizations until resolved by a Federal court in an appeal to repeal. The charter of the FDA in the Food, Drug and Cosmetics Act of 1938 specifically addresses marijuana and retains classification from the Pure Food and Drug Act of 1906 which classifies marijuana and alcohol together as dangerous drugs with a high potential for poisoning and to be regulated by the FDA. This process was ironically pressed by conservatives in the implementation of Medicare and Medicaid long ago, and it is probable that with a federal court's review of such an appeal that the older law would be amended with the exception of marijuana, in any case until this happens government agencies would be very amiss to fail to follow medical advise.
Finally, marijuana has been proven to stop cancer. This is the leading cause of death in the United States and research has shown that molecules in marijuana directly harm cancerous human cells while avoiding healthy ones. My own grandfather passed away last summer after living what the AMA has recommended as a healthy lifestyle for most of his life. It is time for the United States to embrace marijuana and tell the alcohol industry to take some time on the back burner until that 200 billion dollar sore on the American economy has been developed into a beneficial product.
Sincerely,
Paul Andreas Fischer

Letter to Sven Andreasson on his longitudinal study of Swedish conscripts and confounding data

Hello,
I have done some research in nuclear medicine on this subject and there are a number of confounding factors that I believe you have left criminally unaccounted for in your research. To begin with, in states with legal marijuana, such as Canada, use of 5 grams and less per day is associated with an increase in IQ of 5 points. My own research in nuclear medicine looking at the blood flow of the brain supports this, after half a pack of marijuana cigarettes over 6 months most of my brain was normal, with one area with increased activity. According to MRI studies there has been little change in the brain observed, though conclusive evidence exists that the size of the amygdala increases and some indication that the part of the brain associated with addictive behaviour becomes less prominent, here a benefit, though this was not substantial enough to say for certain. Ultimately, biologically what is claimed about marijuana in this longitudinal study is in conflict with studies in Canada that had a high level of accuracy that followed users from 12-17 to 25 and later points in life as well as the most recent SPECT and MRI imaging studies.
The most important confounding piece of evidence does not rely on new technology, or different methodology, however, and it is quite sad that this was not accounted for in this expensive research costing the Swedish government severely. According to the CDC the majority (between 65% and 86%) of schizophrenia can be attributed to the parasite toxoplasmosis gondii. To suggest that something without a logical biological explanation is responsible when it is quite simple how the microbe targets brain and muscle tissue to lay its eggs and the body's protective cysts disrupt bloodflow is quite unethical. The explanation for how it goes in uneven amounts in marijuana users is quite simple, a cat defecating into a potted marijuana plant will contaminate the product for up to a year later.
I do not know the statistics in Sweden off the top of my head, but in the United States 22.5% of people are infected in their lifetime with t. gondii. Of these 25% (5-6% of the general population) get flu-like fatigue and fever, other psychotic symptoms for one week to as long as a month or three months. 6% will have latent symptoms, lasting longer than 6 months and will be diagnosed as schizophrenic. This is the majority of the 1.2% diagnosed with schizophrenia in the USA. It is dose dependant, and getting exposed to the parasite later in life or going thru a period of immunosuppression will cause a recurrence of behaviour.
Please provide an addendum to your research as I have done mine (this came up only as I was publishing, at first I thought to say there were some mild changes, nothing significant from marijuana, luckily I had prefaced my research by emphasizing that marijuana was decriminalized or illegal and the results may be different in a legal setting, as they indeed turned out to be) providing for these confounding factors.
Thank you,
Paul Fischer
