Paul directly addressed this in his reply to Klein (http://paulgraham.com/klein.html); Ctrl-F "the conversion of money into political power"; in brief, he says that if you're upset that economic inequalities leads to unequal political influence, attack that. Fight to remove the political influence that wealth currently has.
If we lived in a world where everyone has the same opportunities for social mobility (i.e., universal free education from daycare to PhD, unbiased hiring processes) and the same political influence (no SuperPACs, no lobbyists, mandate that no citizen spends more than $100 / year on political donations, and perhaps give every citizen that $100 / year, as a use-it-or-lose-it source of funding for whatever political causes they wanted to support)... if we lived in such a world, would you still be upset that Mark Zuckerberg had a lot more money than you? Why?
