Yes, free markets tend to produce unequal incomes. We should not be ashamed of that. On the contrary, our system is the envy of the world and should be a source of pride.

There is nothing inherently fair about equalizing incomes. If the government penalizes you for working harder than somebody else, that is unfair. If you save your money but retire with the same pension as a free-spending neighbor, that is also unfair.
