inequality is freedom. equality is not! So... if you believe in a free society and open markets then inequality is neither good or bad, it is what happens.
I'm not convinced that inequality is freedom, or that equality prevents freedom. Can you explain what you mean by freedom?
Imagine that a group of people, a nomadic tribe perhaps, wanted the freedom to live in a non-hierarchical society. If someone imposed inequality--that the best hunter/gatherer in the group should receive a "fair" share of resources--that would be restricting the freedom of the people, would it not?
