Is your argument that their manufacturing costs would increase by less than 30%? Or that you expect Apple to fold as a company?

You state "they absolutely have the money to run these capabilities in America." Apple's published margin on hardware is 30%, so if manufacturing in America increases costs by 30%, Apple no longer makes a profit selling hardware. If manufacturing increases costs by more than 30%, Apple starts losing money selling hardware.

Big numbers are big because Apple is selling many, many, many phones. That also means that adding to the cost of manufacturing by even a small amount per unit immediately chews up a lot of those outrageous profits.

Apple buys iPhones wholesale from CMs (contract manufacturer) like Foxconn, Pegatron, etc for only $250-$350 and sells them for around $799-$1000 retail. The cost of labor (ie, final assembly; aka, manufacturing) in iPhone BOM, often born by CM's, is around $10-$12 per device.
