Would you both support effective US immigration controls even if it causes a recession and wipes out many family businesses?
Edit: they shut down illegal immigration in Australia (mostly Pacific Islands) and the farmers rioted because they had no one to pick the harvest. It will be a hell of a fight in the US as well if immigration is turned off.
Justifying people living in a country illegally, sidestepping all the immigration laws, dodging taxes, and gaining all the benefits of a U.S. citizen therein because "cheap labor" and "other reasons" isn't really a valid argument. It's cognitive dissonance. It's also bullshit.
Also, so legal citizens in the U.S. now too privileged and snobby for manual labor? Bloodly hell, American was founded on that shit.
