Anyhow, capitalism = saving, investing and reinvesting. You can see more details on my reply to MountainMan1312. It ain’t look that bad as a system, philosophy or even religion.
It’s probably consumption that you are attacking, with all the right and common sense of the world; yet that’s cause by opulence, not by capitalism. It’s true that capitalism create staggering wealth that’s a quite remarkable tendency to then produce opulence (desiring luxury stuff in great amounts for the sake of just having and exhibiting it). But that’s correlation, not causality.
Sadly, you can’t criticise socialism on having a consumptionist society because they don’t have anything to consume at all. They aren’t a superior race or morally superior; they just can’t consume as much as we do with the liberty we do, so they don’t.
