Living in DC area, $500K houses and family incomes of $150K+ just seem to be the norm. I know that isn't true based on statistics, just anecdotal....
I spend time in DC since my wife-to-be lives there. I know what SHE makes, and what most other people she works with make, and it's all well under 150k.
FYI she rents a TINY place for a HUGE amount.
