No one is taking about the millions of Indians that Hiden/Ho will let into the US on work visas and green cards and the massive chain migration from India it causes. And these people never integrate (why would they?)
Sure, illegals are a drain on all resources, but the sure don’t put the middle-class out of work, unless farm labor, meat packing, landscaping, fast-food and construction (ok, here maybe is a problem) is something most Americans can/ will do.
Many jobs you mentioned are what teens do in the summer, plus many others get training for. We need to take care of US first,-not illegals.
