"What I can't understand is, why aren't people rioting in the streets?" I hear this, now and then, from people of wealthy and powerful backgrounds. There is a kind of incredulity. "After all," the subtext seems to read, "we scream bloody murder when anyone so much as threatens our tax shelters; if someone were to go after my access to food or shelter, I'd sure as hell be burning banks and storming parliament. What's wrong with these people?"
