I just watched this TED talk on income inequality. It speaks for itself. Very powerful result. On a whole host of general measurements of social well-being, it is income inequality, not average levels of income that drive social problems. Wow. This has huge public policy implications, which I suspect will go largely unheeded in a society where many politicians are little more than hired representatives of anonymous rich people. (Thank you, Supreme Court, for ratifying the existence of the Super-PAC.)
