"Waaaaa, if we close the borders and suspend ALL work visas, then all our companies will just move overseas." Yada, yada, yada ...
So, let them. And then tariff everything they import back to the USA 100% for the next 40 or 100 years.
"But waaaaaa, Smoot-Hawley, yada, yada, yada ..."
Smoot-Hawley went into effect AFTER the globalists (of that day) had collapsed the economy.
"But waaaaaa, foreign-owned temp service companies supply 437% of slave labor used by companies within the USA, yada, yada, yada ..."
So, tax them at a gazillion percent and drive them back to the mud-hut third world cesspools where they belong.
Submit a bill that would allow American companies to contract directly with American workers, without any threats from the IRS against either the contract workers or against the companies.
This would effectively and immediately eliminate the blood-sucking temp agencies and recruiting firms that have been leeching one third to three forths of income produced by the actual working people in our economy.
