why were highly skilled Korean engineers working “illegally” in USA to begin with?
Most of them say they had valid visas or work authorization.
The U.S. has a visa waiver program where people can come into the U.S. without a visa, and have certain rights similar to visa holders. Many of the South Korean workers have taken the position that the visas they had that allowed them to work for 6 months, or the visa waivers they had entitled them to do temporary work for less than 90 days, and that they were within those time windows.
The lawsuits being filed also allege that immigration officials acknowledged that many of the workers did have legal rights to work, but that they were deported anyway.
So no, I don’t think it’s been shown that the workers did anything illegal. It really sounds like ICE fucked up by following a random tip a little too credulously.
People like to use the example of Crassus’ fire brigade as an analogy for how corporate interests extract value from regular people in society. Crassus and his fire brigade would go around buying burning houses on the cheap, and then put out the fire for the benefit of Crassus, the new owner. There were some who believed that Crassus was setting the fires himself, but the extractive playbook here works whether he was setting them himself or not.
Are agricultural megacorps buying up farms with depressed values and then fixing them so that the values increase? Probably not. They’re in basically the same boat with the price of commodities, in terms of the inputs (water, fertilizer, labor, equipment and machinery, fuel, energy) and the outputs (wheat, corn, soybeans, etc.). It’s a problem for them, too.
Maybe they have deep enough pockets to ride out the current crisis and will have more to show for it in the end, but for now, they’re in the same boat.
