Not everything is available to the rich. I work at an infinitely rich tech company (as many do) and we still can't find people to fill positions, 'cause they don't exist.

Similarly, a poor person and rich person in middle of nowhere Iowa can get the same amount of Iowa (though whoever's less time-poor wins) but neither of them can buy living in NYC.

My point still stands. A dollar isn't worth the same anywhere you go. Looking at national median income isn't really useful.
