Maybe if they’d gone step by step in the 1970s, with more routes (Metro) and more design into communities...it’d work.
I look at the method used in the Netherlands and Germany....with various ‘shadow’ communities that were connected via rapid rail, and they were always ahead of the game.
In the case of DC...they would be doing everyone a favor by moving 50-percent of the government agencies out sixty to a hundred miles from DC.
Move them out even farther..... to separate red states across the country with just small satellite offices in the D.C. area. That would disperse the hundreds of thousands of extremist left-wing federal workers out of Fairfax County, Virginia and put the state back into the red column.
Or shut down 50% of government, move most of the rest out to places like Montana and Idaho, and reduce welfare benefits in DC so the welfare types would move elsewhere and let DC gentrify.
“moving 50-percent of the government agencies out sixty to a hundred miles from DC”
How about 600 to 1000 miles out!
