Who says you don't impose costs on me? In my view I pay for more than I use and since I don't invest in things that are halfway around the world, and since my wealth is infinitesimal compared to many in this country, I'm pretty sure of exactly what it is I do use. Rich people on the other hand probably do not include how much of MY tax money is being used to protect THEIR investments and THEIR wealth. They shouldn't be so sure of their position. In some people's eyes the rich are as much of a drain on society as any street bum - and in some cases they're more of a drain.
