"The growing inequality of wealth and income distribution is both a moral and economic problem. If the wealthy are unwilling to pay more taxes, then this is going to lead to spending cuts. And if you put off the table things like national defense, then you're going to end up cutting more and more out of programs that aid the poor. So, I think there are consequences to this idea that tolerance for inequality requires us to - to just do nothing to make the wealthy contribute a higher share of resources to fund the government."
