And that's good...
I don't understand why people think the gap matters.
If the living standard of everybody improves with a vibrant economy, why worry that your neighbor is making more than you are?
People get stuck in envy when they should be thankful for opportunity and the general wellness that economic freedom creates.
It's NOT rational. It's psychotic viciousness to the Nth degree.
See: "...in the much more virulent cases of hatred, masked as envy ... the creature ... does not desire the value: it desires the value's destruction." and "They do not want to own your fortune, they want you to lose it; they do not want to succeed, they want you to fail; they do not want to live, they want you to die; they desire nothing, they hate existence ..." (Atlas Shrugged.)
