DC makes perfect sense to me as a DC area resident. Cheap housing when measured against income. Sure while we are the 5th or 6th most expensive market, we also make the most money by far making housing very affordable. Housing prices are only about 4 times our income, placing us outside the top 20 most expensive markets when measured against income.

We have the highest percentage of bachelors, masters, and doctoral level degrees by far. Sonhighly educated work force. We also have a culture built around work and careers here.

Biggest tech workforce outside the bay area.

We have a large amazon presence already, and the backbone of the entire internet is here in DC with 70% of the entire internets traffic driving through our data centers.

We have a great public transportation system. We have 3 major airports. We have some of the best school systems in the country.

Bezos owns the Post and the most expensive house in DC...and of course easy access for lobbying.  Marriott, Northrop Grumman and many other companies have certainly found it beneficial to be here for the purposes of lobbying
