Too large an immigration is harmful to the USA. just as it was for the Roman Empire. We need to embark on enlarging the economic pie by making the economics of counties south of the border larger and eliminating poverty in the poorest of the poor: Haiti and others. We need to stop the movement of populations by sending economic progress to these counties. The large movement of populations is a sign of our failure to support these south of the border counties. It makes more sense to support these counties then to send jobs 3000 miles to Asia. It would be cheaper to ship, easier to control end product quality. and it would keep people in there own country.
