I think that the problem is that the political elites in many Western countries, especially in the USA, watch China and falsely conclude that capitalism is much more effective in conjunction with authoritarian type of government. Like in China. Or Singapore. Or many other South-East Asian emerging economies. The strength of capitalism derives from democracy and freedom. Because capitalism thrives on innovation and "dangerous" ideas. Slaves or scared people aren't innovative. Yep, you can produce stuff in China, but the innovation part needs to happen in place where people haven't been afraid to think freely and express themselves.

I hope that I made myself more clear. If people vote for social-democracy, let it be.

Also, I'll give you a few example of why I don't think that the current system is capitalistic. First of all, the zombie banks in capitalism would be allowed to fail. Go bankrupt. The moment we decided to take from the regular folk via taxes to support zombie banks is the very moment in which I'd say we're not capitalists any more.
