You can't rightly support their being permitted to illegally enter the country en masse while simultaneously pointing the finger of righteousness at businesses for hiring them. (I don't support them being here illegally. However they are being employed in MANY if not most cases)
You said the US is at max employment - so who is hiring them to do what?
(https://www.newamericaneconomy.org/issues/undocumented-immigrants/)
We ain't talking no hundred people. There's several millions.
(Yes, I agree. And MANY are working. ILLEGALLY)
Do you want them here just to lay around doing nothing but being sponges soaking up resources? (That's actually not what they do. It's harder to qualify for assistance being illegal than getting an employer to hire them)
Looting and welfare aren't viable options in the long term.
(That's usually US citizens)
Seriously though, all partisan nonsense aside - what are the millions of illegals allowed entry to the US supposed to do to afford food, clothing, and shelter?
(They work and make money and spend it)
Do you have an answer to that question? (See above in parenthesis)
