Thank you. Your comment is calm, on the merit, it is constructive. Despite that you are wrong.

Greed and corruption are not the problem. They are the reality. Humans are greedy, and always will be. The biggest mistake of socialists is an illusion that there is possible to create a political environment that that greed could be eliminated or confined. Good luck with changing the human nature.

Then the question is, which system can better provide prosperity for all, with greedy humans.

If we compare greed to a rushing river, socialists try to stem it, capitalists put it to work on creating the wealth. The rest is history.

I have several articles on this subject on Medium. You may want to peek at them.
