How is someone making $85,000 a year in the "upper class?"

Bizarre.

Because in 2003, the median income in the US was $43,000.

Not enough divisions...I mean, it can be helpful to try to put things into broad categories, but, ya, that definition of 'upper class' is too low here, even for just three broad income levels.

Another point: I would expect these findings to be muddied by the differences in cost of living between areas. $300 a month rent in city A compared to $1200 a month rent in city B for pretty much the same apartment in the same kind of area of town, etc.
