EDIT: Also, how does "Socialism vs. Capitalism" even make sense as a "vs."? I don't understand this. It's an American thing I think. Extreme Socialism and extreme Capitalism are arguably opposing, purely because the absolute extremes of both require absolute power in differing places, but you can very easily be a socialist capitalist state. Many countries are. The absolute extremes are absolutely irrelevant, as they usually are in any issue.

I think what you're referring to would be classed as social democracies. Socialism is a system in which the means of production, exchange and distribution are controlled by the workers. Capitalism is a system in which the said means are controlled by an individual. They are qualitatively different, in the same way a square and a triangle are qualitatively different (you cannot have a triangle with some square properties). Social democracy is simply a form of capitalism which prefers to use Keynesian economics rather than perhaps more libertarian economics.
