Are there any statistics or studies regarding the becoming of these zombies? I thought that the body, if long enough under such medication, becomes incapable of producing its own dopamine, not that the threshold becomes higher.
Funnily enough, psychiatry seems to function a lot like our field, based on trends, because ultimately the brain is a black box. You can't see how it works, you can only feed it input and observe the output, and if it's consistent enough you can record it as an observation.
Apart from the truly severe conditions that prevent individuals from even participating in society, IMHO what psychiatry seems to fail to account for is context. For example, it is said that many people suffer from depression, but instead of looking into the core causes, they would rather just pump patients with meds and hope it gets better with time. Often times though, all that happens is that the patient builds tolerance to medication, so larger and larger doses are needed. It makes me think: what if those people cannot escape their condition to begin with? Can't even know if you don't at least try.

If this is to be believed, regular consumer goods won't matter anymore, and instead you just cater to the wealthy.
