The ruling elite on both sides see illegals as a source of cheap labor. They WANT it this way.
This could be true. I know it was true in Europe. But I’m not that sure what happened here.
As I said previously, the Mexican nationals used to come up across our border in number of about 5M in the early spring. They spread out across the US in five fingers and followed seasonal work and the harvest and helped our farmers get their crops in and to market. Then they returned home to Mexico in the fall. Our economy was good, we could take the hit on the money going back to Mexico, and it helped keep our food supply costs low. They were not a threat to us, THEN.
In the 1980’s Cesar Chavez started organizing in California and Florida, The United Farmworkers Union and began to get sympathy from the liberals who then opened up the welfare state to them and they came and began to squat here. That was the serious mistake.-And then of course the liberals saw the opportunity for amnesty and more votes from another dependent society.
