I worry about the unaccounted soft power of someone with that much money. Through lobbying and market consolidation, the extremely wealthy hold disproportionate political and economic power. At least with corrupt politicians, in a liberal democracy there is some amount to which they are accountable to the people. The power of the wealthy is without account except through government action. laisse-faire capitalists like to hand wave and imagine this power is "not a problem" when it very clearly is, with people like the Kochs wielding their power to sow political propaganda. They did not "earn" that power, or at the very least I don't think people deserve that power even if they were skillful businessmen. For me, it has nothing to do with sour grapes, I don't care that they have more money then I can imagine, other than they can use that money to have a greater voice than me.
