What may be good for businesses may not always be good for their country or its citizenry. I doubt prices would double for the average product, but if a premium is the cost for keeping more of our neighbors employed and off the government dole, it would probably be worth it.
I suspect prices would more than double for many products, notably clothing and shoes, but have seen no numbers.
The problem with your theory is that strict limitations on imports would result in much higher prices on many items, reducing everybody’s net income. IOW, those of us with jobs would have less money to spend on the items produced here rather than there. Less total stuff would be bought. When I might buy two shirts made in China today, I might be able to afford only one made here.
IOW, less total stuff would be consumed and I’m not sure the additional manufacturing jobs would make up for the total loss of purchasing power and standard of living.
Not saying it wouldn’t, either. I just haven’t seen any numbers on the issue, and talking about the subject without quantification is comprehensively useless.
