This is true, at least to some extent. It's the government and welfare that's distorting the supply/demand curve - the immigrant work force is merely a reaction to that and a porous southern border- and of course the border is another government problem. This is a government caused problem, not a business caused problem.
But we still need to get consistent: does a great country provide ALL it's own low skilled labor? I don't think so. Should our immigration policies target the low skilled or the skilled labor markets? I think the answer is obvious.
Until civilized populations started declining, they always provided the full spectrum of labor (from skilled through unskilled); we didn’t import Mexicans to pump gas or work on garbage trucks sixty years ago (and Europe didn’t either). Our current immigration policy is to simply inundate this country with people from anywhere in the world in an attempt to create a rival for two Asian giants with over a billion people each; it is obvious that “work” isn’t even factored into the equation; these people are needed as consumers (of housing, public education, Wal-Mart goods), not workers (we already have very high unemployment). Nancy Pelosi made it very clear that a government check was as good as a paycheck; we’re the ones funding those “government checks”.
Fixed it.
