I've asked this question before, but it bears repeating: if your political philosophy has never been proven to be true, and yet you believe in it with every fiber of your being. . .is that policy or religion? The mantra of the GOP right now is, stop spending, or cut it down to the bone. Cut: education spending, Medicare spending, Medicaid spending, Social Security spending, infrastructure spending. Close the parks! Stop feeding poor people! Privatize everything! And most of all, cut away taxes for rich people and corporations, and get rid of all cumbersome regulations. Because if big companies are allowed to pollute, and don't have to pay taxes, they'll give us jobs! Like magic, everything will get better!  Except. . .
