We used to have a large agricultural labor force in America for hundreds of years, even after the abolition of slavery – they were called Negroes. Then we put most of them on welfare. Not only did this pay better than farm labor, but they got out of the habit of doing menial labor. The women, especially, grew enormously obese due to generous food stamp benefits so they couldn’t do manual labor anymore even if they wanted to, which they don’t. If we hadn’t spoiled our Negroes they would still be out there working, if their other choice was starving. So first, thru generous welfare benefits, we created one problem (lack of agricultural workers) and then created another problem (millions of aliens who will never make good Americans) to fix the first problem. This is like giving yourself malaria to cure your syphilis. Most Mexicans are fine hard working people (at least the first generation before they learn how to be low class Americans with all the bad habits that implies) but they should be fine people in Mexico, not here.
