I don't have a problem with the rich. Provided they are capitalists. Effectively allocating capital is an important role. That's part of how the poor get wealthier. Outside of that (and stability/coherence of political power), what reason is there for rich people to exist though? Because I can't think of any. And typically non-productive beings that exist due to the efforts of others are known as parasites.
