Or how about their children work instead of getting a education , paid for from profits off of immigrants.

Hardly. A lot of businesses are owned by Democrats. And some even by Progressives.

When you're facing a real thin profit margin and you can pay your employees high wages and feel good while you're running yourself into a hard bankruptcy--and maybe taking your dependents on it--you do things that maybe don't sit quite right. Esp. that don't sit quite right with others.

why they are punishing the undocumented workers but not the American business owners who hired them. I mean, I know why: because undocumented migrant labor has been an accepted, albeit illegal, way for businesses to lower their labor costs for a hundred years, and making obscene profits are all that matter to the wealthy class and Repub politicians.

But if they would fine a business $50,000 for each undocumented worker, and actually enforced it, there would be very few hired.

Hmm . . . I bet Rump hasn't thought of this potential stream of income! Or maybe he has. He probably is accepting bribes from business owners to not send ICE to arrest their workers.

Will this ever end?

And now we are having to live with the inevitable. Who would have thought?

Isn't this fun.

Robots pretty soon if they keep doing this deportation thing.

What makes them think ICE wouldn't disregard those documents like they do any other documents?

American workers want a livable wage. We can't afford that. Give us back out slave laborers.

To cheap labor.

What makes businesses think they have to have cheap labor? If you have to have cheap labor to make a profit, there is something wrong with your business model.

to China, India, Mexico, Singapore, or Vietnam....
Where Labor is cheaper.

Who would have thought that the American way of life depended so heavily on the mostly invisible and low paid workers who slaved away in the fields, the factories, the restaurant kitchens and even in their own back yards, maintaining their picture perfect gardens, and nannying their children?
Not to mention the guys who renovate your house, and never show their faces on camera if someone is filming.

Who?
Just about everyone with a few working brain cells!
