Congratulations, you've figured out that the medical field is heavily corporatized. Would you like a medal, a gold star, or a lobotomy?
The issue is you making outlandish claims based upon either the words of one guy, or vague implications of corruption and corporate influence. So some professors made $150k a year because of drug companies. Great, how many of those companies produce ADHD medication? How much of that dollar amount was spent for endorsements of ADHD medication? How involved in research are these men, as it relates specifically to the diagnosis and treatment of ADHD?
All you are doing is making an ignorant, childish ideological arguments, and backing it up not with actual research, but vague conspiracy theories concerning the state of medical research.
Pro-tip: other than one dude, you've got literally no evidence that ADHD is a manufactured disease. Whereas I can produce thousands of research papers by tens of thousands of researchers, that say it is a real thing.
