It is possible that neither President Trump nor anyone else may be able to restore US industry to its former greatness.
If you want to know why, read this report:
Governments do not control the economies of the Western world; corporations do. And many of those corporations don't need or want human workers.
They also don't want to pay taxes, a fact which will leave governments strapped for cash when it comes time to feed their hoards of out-of-work humans.
Frankly, THIS (not "restoring greatness") is the problem we need to address ... and soon. There will be hell to pay if we don't.
