Yeah, a lot of people bitch about capitalism without realizing that capitalism was a significant step up from feudalism / manorialism for most people. When they bitch about capitalism, a lot of what they hate is evidence it's actually drifting back towards feudalism. Renting instead of owning, for example. Or monopolies in control of things instead of there being healthy competition.

I'm all for the Star Trek future, which shares a lot in common with communism. But, it's a future where there is no scarcity. In the present where scarcity is a real issue, communism always seems to quickly become an elite ruling over a population that can't vote them out. Unless someone can prove that there's a system better than capitalism that we can actually get to from here, I'd rather focus on trying to fix capitalism than overthrow it and inevitably end up with something worse.
