Yuppies are rather tragic. They are caught in the middle of the log curve of income utility, which creates an incentive structure that traps them there. On the upper end, the marginal utility of additional work is too low to make linear increases in effort worthwhile. On the lower end, the marginal loss of comfort is too high to risk non-linear gambles. Yuppies are trapped in their own middle income trap, so they play a different game: the orthogonal game of social status.
