Globalization was the death to Gary, Indiana and so many more mid-sized American cities.
Globalization destroys whatever it touches, along with other aspects of leftism.
The U.S. steel industry declined for a number of reasons. Foreign competition was only one of them. I'll list a few more here:
1. The completion of the construction work on the Interstate Highway System (bridge construction was a major part of the domestic market for steel).
2. The use of plastic, fiberglass and composite materials for auto manufacturing in place of steel.
3. Technological obsolescence of U.S. steel factories, tied to #4 below.
4. A fascist business model involving management, labor and government that kept obsolete steel plants afloat long after they should have been upgraded or replaced.
5. Domestic competition from new U.S. steel mills.
Item #5 is a big one that doesn't get nearly as much attention as it should. As one industry representative said at a North American trade conference a few years ago: "It's not 'globalism' when a company closes a steel mill in Ohio and opens a new one in Alabama or Texas."
