Cap vs Com: Who gets to be master race (those w cash & those w/o cash, respectively) and who gets to be sub-human.
Basically good ideas (free market, treat ppl as humans), but impractical alone; they start going to extremes (all-powerful multimegacorps, thought police).
Best thing would be to combine them. After all, big corps tend to be sociopaths, as do bloated govs.
Problem with that, tho, is whenever a good idea is to be implemented, some 4 times out of 5, those in charge insist on doing it each and every wrong wayfirst... >_<
