In the movie average guy has been transported into society of stupids. But if you’re genius, you see all the idiocies of modern society, all the stupidity of average Joe, and you have no choice but to play the stupid game of life in accordance with dumb laws that this dumb society managed to create
People being stupid isn’t a problem or bad necessary.
The problem is when stupid being engage in collective delusion and damage/destroy the principles and needs that build society. For example, the belief that taxes are theft, rather than the cost of social infrastructure that makes their private businesses and lives even possible.
