I'm not going to disagree with your points about capitalism, overstimulation, and needing labor unions and a better world - those are all fair points.

However, I also wouldn't go so far as to say "you don't need stimulants." If the effect of stimulant medication only boosted productivity, sure. But for me, stimulant medication is more about improving my working memory, I don't feel a burst of energy to get me through the jobs I need to do, I'm just not fighting my own brain and poor memory as often. I'm an adult, and I do take days and sometimes weeks off from taking my meds, either because I forget to take it, or occasionally am overstimulated because of the hellscape we live in, and know more stimulation will make things worse. I don't think the "must take stimulants every day" thing some do to themselves or their kids is healthy either. And I think it's bad if you are only taking stimulants for the sake of meeting expectations of those around you. But if they help get your brain struggle less on the things you actually care about and want to do, there shouldn't be any shame in taking them.
