Perhaps they have a point actually: if we assume that a significant proportion of society is retired with savings (and this is the case in the US - ~1% of population can afford a rich lifestyle on passive income alone, and ~5% can afford about a median lifestyle), then serving society may become a calling for those people - they need something to do after all - once everyone will understand that normal "jobs" became mostly harmful to society, or if not harmful, so poorly paid that anyone with even $2M in stocks will not be interested in doing them.
