As for the claim about Exxon/Mobile being a cause for poverty, I would like to state that drug companies make a much larger profit margin, in particular th Pfizer profit margin in 2006 15.7% VS Exxon 10.6%

While looking for the side effects of taking anti-depressabts, I found this evidence of corporate greed:

Since 1988 the pharmaceutical companies (starting with Eli Lilly, the manufacturer of "Prozac") have advertised to the people (direct to consumer) as well as to their family doctors, that if you suffer from depressive feelings, you must have a "biochemical imbalance" in your brain. The advertising finger was pointed at the neurotransmitter "serotonin", and it is used to explain nearly any emotional problem a person might have nowadays. Many other pharmaceutical companies came out with so many variants on the SSRI-antidepressant to try and capitalize on its popularity, by spreading this theory even further amongst the people. Theory? Yes, only a theory!

The Truth is that nobody in the medical field really knows if a "biochemical imbalance" is the cause of any mental disorder, and they do not know how even the hypothesized "biochemical imbalances" could produce the emotional, cognitive, and behavioural symptoms that characterize any mental disorder. Clever marketing tactics exercised on us by the pharmaceutical industry, prevailed above scientifical evidence and research. Greed, dis-respect and contempt of the population, prevailed above altruism, medical care and responsibility. It's the greatest shame of of this era. More information:
