On the other hand, focusing obsessively on the Midwest/Rust Belt at the cost of the Sun Belt is a terrible idea: one region is predicted to have strong economic and population growth over the next few decades, the other has been on the decline in both (it LITERALLY has the word "rust" in the name.) People love to fantasize about Making Michigan Titanium D Again, but that's like investing in a record plant.
Err Wisconsin and Minnesota are actually doing pretty well. AFAIK Iowa isn't doing half bad either. It's mostly Michigan that is doing poorly.
Minnesota is actually the wealthiest state when you adjust for cost of living.
