This idea dc is a company town isn’t really true & the company isn’t going out of business, 20% of the workforce is federal government, if they cut 25% of the federal workforce it would be 5% of the region and of course the vast majority are of these people would get jobs in the private sector, not to mention the government will probably have to rely more heavily on government contractors to fill gaps where the cut.
