Cutting corporate tax rates can have an effect similar to that of tariffs but without the "trade war" issues.
Wishful thinking....
GM and Ford and others have spent BILLIONS to build factories south of the border, labor costs which are typically 70% of expenditures in most industries are far lower in MX... You aren’t going to repatriate the jobs by simply cutting tax rates on corps... That will encourage repatriation of the earnings, but it won’t move the jobs.
You want those jobs back here, you have to make the cost of producing them in MX higher, and the only way you can do that is by adding tax into the retail cost of the product at a rate higher than the labor and regulatory cost differential.
The US could offer a tax rate of 5% for 25 years, to any manufacturer which opens in the US or expands in the US. There should be no preference for union labor, the idea is to create jobs, not grow unions.
Yes, cutting the tax rates and burdensome regulations will do a lot.
