Is there such a thing as a capitalist economy where everyone wins? I think not. Capitalism is zero-sum. There's no such thing as making money, only taking money, so for you to "win" at capitalism, someone else loses. Those extra dollars in your pocket come from the people who lost to you. Everything you have comes from someone else's failure and your billion-dollar empire is built not on your MBA and good instincts but on the blood and bones of the enemies you didn't even know you had.
Consider it on a smaller scale. You have twenty people locked in a room for a day. Nothing comes in, nothing goes out. No matter what they find in the room, what they buy or sell between themselves, no matter what they do, it's a closed system. The same amount of money is coming out of that room at the end of the day as when it began, even if it's all in the pocket of one guy. He might think the system works, and it did, but only for him.

PS - You can print more money, but it represents the same total value as before.
PPS - And all of this is why we need governments that stand up for the poor.
