Capitalism is the only economic system that works.

"Capitalism works well because it is in tune with our nature. Adam Smith called it “the natural order of liberty”. Everyone selfishly desires to provide for his needs. To pay for what he wants from others – services and goods – he has to provide something that others will pay him for. Millions do it, and the result is prosperity. Capitalism is an abstract machine most beautiful to behold in the wonder of its workings. When individuals have the incentive to achieve, acquire, and enjoy something for themselves, they’ll go to great lengths to afford it. They’ll compete with each other to provide what others want, toil to make it the better product, and set the price of it lower. The best is made available at the least cost. Everyone is both a taker and a giver, and everyone benefits. True, not everyone’s effort always succeeds, but nothing stops anyone from trying again."
