Sure the DC region will long boom due to The Company, but the city itself will be pretty screwed if Metro is allowed to rot. While slightly less true in DC than in other places, generally the powers that be don't use public transit and don't understand its importance. Even when filled with white people in suits, as Metro often is, it's still seen as a lesser option.
If only there was some entity in the Washington, DC area with the ability to print and spend as much money as it wanted...
