That's a real good observation, Ron: reducing exploitation and raising pay for everyone on the low end. Exploitation always pits one group of the poor against another... usually along racial lines.
Reducing illegal immigration could possibly raise all boats. At least that's more likely to benefit the poor than the "trickle" down" theory. Make me richer and the crumbs from the table will be better.

Ultimately, this is more of a humanity and justice issue than a political issue. Politics tends to offer two inadequate choices with the selection based on emotion or prejudice. The one who can make people hate each other holds the power. I know Little Hawk sees it this way, too.
