content: Eh...he doesn't exactly disprove that poor people make dumb choices only that even if they make smart choices they will still be poor.  The objective was never to suggest that there aren't genuinely shitty people who are poor. The point is to refute the belief that "minimum wage" is actually a livable wage, and that the social narrative of "work hard and do all the right things and you'll raise yourself up by your bootstraps" is false. So the fact that "even if they make smart choices they will still be poor" is the alarming possibility about the situation, highlighting that maybe it's not the person's fault that they can't get ahead, but maybe something more imposed.
