You're wrong, Check the statistics. And slavery doesn't exists in the West, especially in America... Do you know the definition of Slavery?.

You may don't want to... But rules are the rules and in a Capitalist Country we need to play under Capitalist rules, same happens in a Communist Country where we need to play under Communist Rules.

Your third point is only Anecdotic Evidence, and doesn't prove anything, meanwhile there are statistic that demostrates what capitalism did for the world. Also, Should I repeat that I don't think that Capitalism is a perfect system?.
