I think that you make noble statements, and I understand what you say.
I think that the idea of socialism is a splendid one in a perfect world, which sadly this is not.
Unfortunately the human race is inherently greedy, hence what we’re doing to our beautiful planet (socialist or otherwise). Also, history has shown that socialism doesn’t really work that well - the mantra “Everyone should be equal, but I’m in charge” kind of contradicts the ideal really.
Having said all that, the extreme capitalism of many western countries makes me feel very pessimistic about the future of the human race and life in general.
Perhaps a mixture of both is the way to go?
