Housing in DC didn't have the crash that the rest of the country experienced, that's true. Of course, neither did Houston's, or San Francisco's, or much of New York City's.
By contrast, people who don't live in DC didn't have their pay cut 10% by mandatory furloughs demanded by a governing body they have no vote in. People who don't live in DC get to pass laws determining how they want to live, without those laws being vetoed by representatives from Oklahoma who find them politically inconvenient in their home state.
I haven't even touched on the fact that DC's population is over 50% black, and has been for decades. It may not be the case now, but in the past the arguments for refusing DC residents the right to vote were very explicitly racial.
