That’s one heck of an accomplishment. You have to give him credit.
It will take a while, but businesses will start moving back into Indiana, and it will become an example the surrounding states simply won’t be able to ignore.
The only question is if they can hold out long enough.
Michigan’s industrial belt (the I-94 corridor) is only about 40 miles from the state line.
I don’t know if its even there anymore but Grumman Olsen used to be a big employer in Sturgis Michigan within sight of the state line. It would be relatively easy for them to step across the state line. If not the entire factory, plenty of secondary operations.
