I voted Capitalism, simply because eventually a few philanthropists will give back what they had taken, but is impossible in a "Communist" (the governmental form, not the economic theory) society.
The thing is, I much prefer Socialism, because, while I like being able to advance up the ladder at my own pace, I also want to start off on an even footing with my neighbor, with his neighbors, etc. Basic Socialism is different from basic Communism, however, you simply cannot have a pure economic system. You cannot have a purely Capitalist system, as eventually our human compassion will kick in and we'll say "Protect the workers!" or a purely Communist system, as eventually our human competitiveness will kick in and we'll say "Give me more shit I don't need so I can show off!" Socialism makes sure to provide all with the basic means to start off. As in, a poor person need not stay poor simply because he was born so. The government is tasked with paying for housing, utilities, education, and healthcare. That doesn't (or at least shouldn't) mean that they'll pay for it forever. Just until you don't need it anymore. That doesn't mean you won't still pay taxes, you'll just have a larger house of your own.
What we have here in America is far similar to Socialism that it is to Capitalism, however, it's not great, or even good, as some people still think we're Capitalists, and refuse to pass any laws that make us "Communist" (See: Healthcare, Education), and refuse to raise taxes, even though the potential revenue is just the windfall we need to get the government back on its feet.
Side Note: Eff you, you ARE going to pay taxes anyway. Better your tax money go to furthering human progress than lining a politician's back pocket, eh?
