Detroit was the hub of the auto industry. Outsourcing and foreign competition hollowed out the central city (which deliberately didn't have public transit) and left gigantic abandoned houses and skyscrapers throughout.
There has been massive public investment and popular support to cause a revival of sorts in the city and is a success story.
Go look at some photos from like 2010-2014.
This happened throughout North Carolina where I live when textiles and furniture manufacturing was off shored. I assure you it wasn’t over building that caused the same outcome. It’s almost like the is an alternate explanation that is the common thread. What could it be?
Such short term issues from massive economic collapse suggests building more housing works.
How was the work outsourced around that timeframe? Do they no longer have an auto-industry at all in Detroit, or is it just greatly reduced?
Detroit was pretty much the place where cars were designed and manufactured in the US at one point in time. The highest producing factories, the engineering, the management, most of it happened practically inside the city. Over time these auto manufacturers opened plants on lower cost of living places, spreading out across the Midwest while a lot of the engineering and management still took place in Detroit.
People often point to foreign competition for the downfall of urban Detroit but the writing was on the wall and decay starting well before foreign imports made a big splash. Between 1945 and 1957, GM, Ford, and Chrysler built 25 brand-new auto plants in the Detroit metro area. Not a single one was built inside the city limits. They weren't building these factories overseas (yet), they were building them in cheaper parts of the US. Detroit lost hundreds of thousands of well-paying factory jobs well before Volkswagen and Toyota started selling things in real numbers in the 1960s.
