What I don’t understand is why corporate America is against immigration. So many big businesses rely on the cheap, willing labor of immigrants.
Corporations and ice goal not to deport all the labor they are the whip to make sure the labor doesn’t get ideas about joining unions and reporting exploitation. It would be pretty easy to fine and close down businesses who hire illegals but they dont.
They aren’t. However, they need to blame someone for the ills of society that they cause by taking all our money, to make us angry at the wrong people and let them keep taking all our money. So they choose immigrants, because xenophobia is a natural human emotion and easy to exploit.
Also, strict immigration laws and the constant threat of deportation can be used to more effectively exploit immigrant workers.
Very important part of the machine.
Better for Elon and the gang if there’s race warfare rather then class warfare.

The thing is, they aren’t against immigration, but there’s another kind that let’s them exploit workers more. I think it’s the H-2A visa that there was a recent case over, and basically it’s decided they can be treated essentially like slaves, maybe even worse than slaves were sometimes treated.

The way the visa works, from what I recall, is that they can only stay in the country while their employer allows them and employs them. This means they can’t negotiate for higher pay, or anything else. The employer, in some cases, will feed them almost nothing (one case I think they were feeding them one bologna sandwich a day). IIRC, there are companies who control them, and they loan them out to other companies for labor. It’s not technically slavery, but it’s practically the same.

They want to deport people who aren’t working under this visa so they can have bring in people under the much more exploitative one.

Illegal immigrants are easier to exploit than legal immigrants.
Companies will be for or against something based on how they think ti will impact their profitability. Tech companies are very much for more immigration of HB1 visa.
