In history "immigrants," operates in a predictable manner.
Multiple generations from a villge in Ireland, Sweden, Italy and Mexico move to a place in America, where their relatives have successfully gone.
In the 11800s, they exchanged letters. Today a fast food store operator might ask a good employee, if he knows of some good workers, back home in Mexico.
If you go to a local fast food place in America, ask around, you might learn that what I stte here, is true.
I have done so.
I have also learned from guys that I grew up with in suburban SoCal, that many had grandparents that started as seasonal agriculture workers, until the ranchers/farmers provided for year-round family housing.
The first wave of Swedish settlers (mine) in Minnesota, and the first wave of Scots Irish settlers (mine) in NewEngland, all wrote letters to back home when they were establsihed. They said come on, were are doing well, and you can too.
My wife's mother and father's famillies were from the same village complex, in Italy. Her mother came in an old world arranged marriage. Four generations later, not a single criminal.
I am okay with a narrowly defined DACA program.
