If this is even remotely true and we eventually can't have our Big Macs and "need" more workers... We should first we've exhaust the available American welfare, student, prison, etc. populations.

Then, at a minimum, no foreign workers until the process is secure and it's only that one worker.
No relatives, no family, no anchor babies.

As it largely appears now, whenever someone comes over with or without a work visa, legally or illegally, so comes the entire family. And eventually extended family.

So, one person might be working while the rest of the family is bilking the taxpayers and having more children on U.S. soil.
