Most of the sites linking Psychiatry/Psychology to the NAZIs are Scientology fronts. Just be sure to verify the authenticity of the information you're getting. The "therapy" at CEDU or other Synanon based programs was a product of cultic trial and error experimentation, not some govt. conspiracy. Cults have existed for a long time and the methods of brainwashing used in China hardly originated there (but they coined the term).
If you've ever worked with the govt, you'd agree that they're far too incompetent to get anything simple done, much less some grand conspiracy. 500 dollars a hammer is because the same people buying the hammers will retire and start selling them. It's in their interest to keep the cycle going. It's about greed 99.9% of the time. Lots of stuff is classified simply because it's unbelievably embarrassing (eg: the "gay bomb") and the public would be outraged if they knew their govt was wasting their money on "defense" which has basically become a welfare industry. MK Ultra was a disastrous fuck-up. It wasn't sucessful at all. Instead of seeing what would happen to people on large doses of LSD they should have just taken a page from what cults were already doing. It does seem as if the govt is getting a clue, though, since reports from Gitmo seem to indicate similarities between what they're doing to the prisoners there and more or less classic thought reform.
While I'm sure there is some govt. personnel benefiting or involved in some manner with what goes on in programs, it's hardly a conspiracy and more the classic case of special interest groups pushing for their shot at the government teet (eg: programs getting contracts from the state, etc...).
