Sadly enough a lot of doctors are complicit in it, after all a lot of doctors didn't get into it out of altruism, then again the same can be said to apply to a lot of developers, lawyers, and several other professions. My comment was in no way denying that our society is messed up.
Just please don't equate a medical profession and body with nutritionists, that is just grossly disproportionate and just outright weird. If you like I can have a rant as to how little we understand cell uptake pathways and metabolic pathways another day.
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.
