Good point. In fact the salient point.
Like Ghost of Philip Marlowe noted if there were no criminal invaders to do jobs at below living wage wages, the wages would have to rise to survival level and the Citizens would then do the jobs.
Some make the point that sending back the illegals would ruin the economy because jobs would not be done.
I think if the 22 Billion $'s the illegals sent back to Mexico last year had stayed here that would help the economy.
Good points...
