What a crock. They're doing jobs that Virginians won't because they've depressed wages to the point where it's still attractive for someone here illegally who would be making a lot less back home.
Of course it's baloney. As it usually does when left alone, the market will solve that "problem" once illegals are not part of the equation. If jobs need to be done, the market will find the level of wages needed to attract the appropriate labor to perform them.
The various entitlements provided by government also must be appropriate to provide sustanance to the needy without being too great so as to discourage the desire to work. i.e. don't pay people as much for doing nothing as they would get for working basic jobs. There must be some incentive to work.
