I visited there last spring.
I noticed a multiplicity of men in $1000 suits and women with $400 dresses, handbags, and shoes.
Life IS very good in the beltway.
OTOH my cousin who lives in Georgetown paid $800,000 for a home that would be $60,000 here in Indianapolis.
It costs a lot to live in some parts of DC.
Mostly west of the park, but urban pioneers—Whites, are moving back in and driving the shadow out into PG county.
Just because someone pays something in the DC area does not mean there's any 'wealth' underlying the price.
