YOU ASKED: "Illegals are the lowest paid workers; that has been well advertised. So, how do they send so much money back to Mexico?"
I answered with a link that explains that wealth can be created, and it is not something that can only be rearranged.
There is an assumption that these workers "steal" the wealth that would otherwise go to American workers. This is not true. THESE WORKERS CREATE WEALTH. And they create an enormous amount of wealth in America. This is the answer.
Everybody else forgive me now. I have to go back to work.
