It's all about perspective really. Capitalism CAN work, but it's actually at it's best when people maintain their morals, but frankly they don't. It's biggest strength becomes it's biggest weakness too. Economic "freedom" doesn't always have to mean screwing people over. Capitalism does bring in more innovation. I don't think we'd have any game consoles or maybe even the internet if it weren't for capitalism. Well actually I could see the internet being invented, just not the same way it is now. But game consoles, not at all.

I do think right now most people are used to their only motivation to do anything being money. So most likely as time went on people would find other reasons to be creative and invent useful things other than getting rich right
