I am 100% sure that there will be jobs in all those above mentioned states in the future.
But your post does point out the dysfunction on their economy. A recession, even a mild one, is likely within the next four years. Of course the rust belt will be hit hard, than in the next election they will all vote solidly Democratic.
No party has the ability to solve it. They will basically just have weak economies until climate change makes their areas attractive.
Not 100% of people will be unemployed. Stay the course!
But seriously, we're going to need massive socialism as large amounts of jobs are offshored or automated and all the money keeps going to the rich.
Job losses due to technology are vastly over stated.. but I do not feel like arguing right now.
