I guess I was talking about everything that factors into making a place qualify to be referred to someplace that "wound up" like Detroit. Loss of jobs, loss of employers, eroded tax base, bad real estate and well... historically speaking, as Michigan pretty much revolves around Detroit, boat production. Perhaps you meant something else. If I misunderstood, I apologize.
My guess was that a reduced capacity or "wound up like" status Detroit/Michigan production level of
anything would be more than the total GDP of Washington, NC which has a population around 13,000 people and a per capita income of around $14,000.
I do a lot of business in Detroit. I have never been to Washington NC, so I admit that I could be guessing way off. Washington NC looks very beautiful.
I hope that helps.
