I have noticed that many of the Central Americans in New York and Florida took many of the jobs (domestics, kitchen help, busboys) typically reserved for family members or blacks. As family members have gotten smaller and blacks have stopped working such positions, the Central Americans have taken their place, at least in the areas that I have lived.
Every other weekend at my place in So. California. Of, course the missus and I have to do it, the kids wouldn't think of it except for the money, and if we went that route, the immigrants would be cheaper. {;~)
