You know, it strikes me that it doesn't have to be some huge conspiracy with millions of people keeping secrets. It could be a few bureaucrats who know a few people at Pfizer and who help suppress certain types of studies to keep them from being authorized for use. For example, if the FDA will only accept randomized control studies vs. observational studies (even though the Cochrane Library has shown that, on average, over thousands of clinical trials, over decades of research, OCT's and RCT's reach the same conclusions) and RCT's are 100x more expensive, then the only groups who have the cash to do studies which the FDA may approve are the large Pharma companies. It is the same principal for regulations in the power industry. TVA, Florida Power and Light, and Southern Company don't care if the government mandates astronomically expensive regulations, because they can pay them, and any would be competitors that would be new to the market can't.
