I think you lost the thread (literally the context of threads I was responding to), because much of what you’re saying aligns with my point. OP was mocking the idea that environmental factors should be taken into account and advocating a no-excuses policy of individual responsibility.
If you think I am advocating medication or implying that “people” are helpless against corporations, read again. I agree with most of what you say although I am not sure we need more research (although of course I don’t discourage it). Maybe one day we’ll prove that the government subsidizing corn so that big corporations (spun off from former tobacco companies as another comment pointed out) can super cheaply mass produce syrup which our evolutionary biology finds difficult to resist and market directly to children turns out to be bad for health outcomes and good for profits (for the medical industrial complex as well). Oh wait, we already know that.
