Goldilocks, you need to put more thought into arbitrary manipulative exchange rates…
A $50 imported screw driver, $50 coffee mug, $50 can opener, a $10,000 TV set, and a $90,000 Toyota, would force people, the unwashed many to stop buying imports because it can be made far cheaper in the USA.
Anybody local could open up a screwdriver factory, make them for $5, instead of $50 imported from China et al, and hire people. Many manufacturing businesses would open up all over the USA.
