Of all political systems, democracy is the best because it gives people freedoms. Democracy still sucks, but the rest is way way worse.

Of all economical systems, capitalism is the best in the way of generating resources because it gives people freedoms to trade directly and find ways themselves to find the most efficient ways of producing goods. Yeah, it sucks too and has lots of failures that CAN be addressed but nothing comes even close to it.

Evidence? Look at all capitalist countries, look at non capitalist countries. Look at Russia for a nice communist example. Communism was implemented and promptly they had a famine. That is on too of all the torture and killing requires to keep its citizens in line. The why you can look ip yourself. Watch the movie "the chekist 1992, always a fun demo. It stayed a shit hole that kept torturing it's citizens in golulags to keep them in line intil it fell apart in the 90's, and went to a capitalistic economy and promptly Russia started growing. That is until mobster boss Putin got his greedy little claws on it but that is a different story

When Europe was in shambles it rose back up within a decade thanks to the Marshall plan which pushed capitalist economy back in running. Because of capitalism Europe is the second most powerful block in the world.

Look, capitalism on itself sucks. I fully agree. But you can't deny it's power. So you do what Europe does, use the power, limit it, and use the output to give a nice socialist society.
