Absolutely true. The rich people in the red states want the undocumented for cheap, disposable, exploitable labor. The rich people make their money from this exploitation and with that money, send their own kids to college. This will help ensure that the children of the rich will NEVER have to compete in the job and housing market with the present and future population bomb that THEY are enabling the creation of. And ironically, that bomb will grow up to vote blue, also.
It's really NOT a matter of blue or red. The net result is that rich people are selling out poor citizens of ALL colors and replacing them with newcomers of Hispanic descent.
That is EXACTLY what has happened to California. Not so long ago, a very red state.
