[Fallout 4] So how's D.C. doing?

Also, how are the other east coast cities faring?

The Brotherhood at least seems to be doing extremely well. They've got The Prydwen, a ton of Vertibirds, seemingly unlimited numbers of soldiers and T-60 suits - which implies they've set up manufacturing for these things as well as become stable enough that the people of D.C. are willing to join up.

Given their practices seen in The Commonwealth, it's likely they've annexed the farms that cropped up around DC, so life may have become harder for the average person, needing to supply both themselves and the Brotherhood. But, they may also receive protection from the BOS to ensure they keep producing food - harder work, but safer from raiders/mutants/ghouls.
