Apparently it's going on right now.Before ya know it there will be 11 million or so fewer people in the US. So what do all the rich folk do about their nannies and pool cleaners and gardeners? Replace the cheap labor with "American wage" folks? Or sneak more undocumented workers in? Get rid of all the undocumented workers except for those they need to do work for them? T'is a dilemma. Indeed t'is! :(.
