America has a long history of denying civil rights to its poorer "non-citizens" for the economic benefit of the priveleged classes.

First American Indians, the black slaves brought from Africa, now Mexican and Central American "illegal" immigrants.

Let's conveniently ignore the fact that the Mexicans are working in the US. That over 10 million "illegal immigrants" are here.

They are illegal, not citizens, and like the slaves of an earlier generation, are put in a position in which their labor is gladly accepted, and they are given no rights.
