I’m wondering what the cost of living for the uber-rich really is. They already own outright everything they want, so living costs are just a matter of consumables and maintenance. Don’t know about Buffet or Gates, but am sure Jobs’ costs are pretty low, as he lives a turtleneck-and-jeans, modest 5000-sq-ft home, washes-his-own-dishes-by-hand lifestyle; just cash in a few stocks on occasion as needed, making his taxable income very low.
FWIW, I don’t care what their cost of living is. I’m not entitled to what they’ve got. Period. I stopped buying into that class warfare cr@p many moons ago, and not because I became wealthy :-)
