That sort of society has a slew of issues that could be better explored in futurist science fiction (things such as psychologic issues for the non-producers, the sustainability of altruism, etc.). But it is a consideration that I have thought about.
Capitalism isn't going to be subverted that quickly, though. The system will right itself and any revolution of that caliber will be long and hard fought. The world superpower will be a capitalist system in 2050 and probably 2100.
