While I agree, the difference with the jobs you mentioned is they require actual skill. People can learn the trade if they really wanted to. Donald Trump and his entire cult are technically smart enough to pick oranges. I worked 1 day doing it to see what it was like. It SUCKED, climbing up and down a ladder all day left me struggling to walk for a few days. But any idiot could do it.
So when the illegals are gone we're gonna be fucked when it comes to oranges, I don't think people really understand how everything will change. A 5LB bag of oranges up the street is $6. When we lose the illegals a 5lb bag will cost as much as meat. That's assuming we can even buy them as they'll have to figure out a way to pick them with every legal person refusing. Same thing for all the Strawberry patches out here.
Alot of meat is cut by migrants now already.
You don't think Walmart, Dollar General Market, I have never been in a Whole Foods. It is all pre cut, people just put it out and rotate it on the shelves. It was cut at the processing plant. Good seal on the package to keep the Nitrogen inside to keep the Bloom Effect. Which is basically when meat is cut fresh it is dark, oxygen hits it and it blooms to the pretty red color. Then it used to be wrapped by a person whose job it was to just wrap and price label and stock it on the shelves.
If you don't see an actual person cutting the meat, like a window with a table and band saw, it is probably prepackaged.
Even then the boxes come in bulk as a Chuck Shoulder, a Round, a loin, and a Rib section. Experience is needed to cut a bone in sirloin at the right angle to make that bone the smallest.
