I don't buy this view that pharma companies are the bad greedy ones, and psychiatrist are noble wise doctors participating in clean science.

Pych doctors more than willing participants in the prescribing of stimulants and mild euphoriants. They get rich also doing so - 4/5 $200 appointments an hour is common, and if you look at the highest paid public employees in some states you'll see state-hired prison and other psychiatrists towards the top below university basketball coaches.
