And we're back to communism again. This thread has nothing to do with communism. That you keep going there shows you can't have a serious conversation; goodbye.
It's funny, you're arguing for progressive taxation, but you don't understand the history behind labour movements, equal rights, welfare, socialism, etc... Or why communism is relevant in a discussion about rational choice, inequality and perceived fairness.
I do get it though - Americans have been taught to hate communism, and thus have purged an entire century of socialist philosophy from their collective thoughts.
