While it is understandable to think that immigrants are "taking your job", it's the capitalist that is giving your job to that immigrant instead. So realize the real enemy, it is not the guy who takes half of minimum wage under the table that is your enemy, it's the boss that does it.
Unfortunately many people fail to realize that, because the elite do not want you to look at that part. I have a friend who immigrated to Netherlands, working in a very big global company, and the amount of money she makes isn't even enough to cover her rent all by herself, so she lives with roommates whereas the friend she has that does the same job but Dutch, makes nearly three times the amount she makes. You think immigrants are fine with that? They are only accepting because that's the best they are offered, if they reject, they will not make any money.
You are again shifting the blame from a majority of individuals onto a tiny minority. You are doing the same that you are accusing others of, just the inverse of it. If there is no migrant that is willing to take the lowly paid job, the wages for those jobs will increase. Jobs can't be indefinitely left open, that's not how things work. One of the main reasons why wages have stagnated is the endless supply of migrants who will take any job at any pay because they have no qualifications for something better, and because they don't understand that this hurts everyone including themselves.
Many companies are complaining about dealing with a shortage of workers, if immigration stops. On the other hand, many people are talking about the AI revolution creating mass unemployment. Which one is true? Will there be a growing demand for workers, or there will be an increasing unemployment rate caused by AI? The two statements are contradicting each other. If AI creates mass unemployment, this means that we clearly don't need any immigrants. What's the point of importing cheap but unqualified labor, when the factories of the future would be full of AI robots?
It is coming, it just needs another couple of years or a decade. The first commercially successful general purpose robot will make a huge change here even if it is going to be inefficient and expensive and have errors as a first product normally does. This will lead to a revolution in robotics. Watch this

An AI robot would be 10 times from productive than any immigrant coming from Latin America or Africa.
This is an understatement even if some Latin immigrants can be really good workers.
You keep on talking down on people because of where they come from. And always brandishing this data like a trophy. Who destroyed Iraq, Libya and Afghanistan? Read about how the US backed the invasion of Somalia, which has destabilised that country. America and its allies keep intruding in the internal affairs of other nations. There wouldn't have been many people seeking to leave their nation if the US had not contributed to wars and conflicts. The invasion of Libya affected the security and economy of Africa and led to an increase in migration. What was the offence of Muammar Gaddafi?
Now, Trump wants to attack Venezuela for nothing. If Venezuelan refugees begin to enter the US illegally after these attacks, you and others will begin to revolt. As long as the US doesn't mind its business, it might continue to suffer from the repercussions of its failure to respect other nations' territorial integrity. If you want people to come to your country, leave them alone.
Talk about a whataboutism. Sure I have no problems agreeing with the fact that US is largely responsible for destroying those countries. Does this change the fact that most immigrants from those countries are uncivilized savages and criminals? It does not. Both can be true at the same time.
You cannot move American Crops of tomatoes, peanuts and chillies from the United States to China or other asian country to be harvested by the poorest people on the planned, for obvious reasons.
The fact is, most American citizens do not want to work harvesting tomatoes under the sun, specially if they are getting paid less than minimum wage, as immigrants are paid. Even if companies found citizens who would like to take such a hard job, it is unlikely food companies would absord the price difference, they will opt to transfer the price to the final consumer instead.
Eventually, the United States will need to open to immigration again, when presidency changes.
No, most of that workforce will be replaced soon. They are not necessary and are 1 technological jump away from replacement.
