It reminds me a lot of where I grew up in Portsmouth Ohio only on a smaller scale. At the turn of the 20th century the town was a busy commercial hub on the Ohio river with over 100,000 people. When my parents moved there in 1963 it was down to 49,000 and when we left for California in 1977 it was around 25,000. Now I think it's somewhere less than 20,000. Growing up there I saw the steel mill close down, a major shoe manufacturer left and a uranium enrichment plant closed as well. Pretty much for the same reasons as Detroit, unions demanding higher wages until the factories said fuck you and moved overseas. All of the schools I went to as a kid are gone. Now it's mostly retired people with no place else to go and people on welfare. Lots of big beautiful victorians and estates that can be bought for cheap, but nobody around to buy them. It was a great place to grow up but it's not the same place now.
Ironically Portsmouth had one of the first professional football teams called the Spartans. They moved to Detroit and became the Lions. The stadium they played in is still there and my brother played HS football there.
It's sad to see how the US has gone from the manufacturing leader of the world to a nation of consumers. It's only going to get worse.
