BS. This is elitist code for Americans are lazy and stupid, a justification. Pure crapola.
In any economic transaction, the person who functions in the "seller" role is almost always going to be selling a product or service to a "buyer" who has a higher standard of living. That's why a laborer working as a landscaper, for example, is never seen mowing lawns and trimming shrubbery in his own neighborhood. By definition, he will always be dealing with a clientele who values their time more than the money they pay him.
You can translate this to almost any occupation in any industry.
What we're seeing here now in the U.S. is the natural/inevitable result of what happens when our standard of living is so high that it's hard to find "sellers" whose products or services can be sold to "buyers" who are willing to buy those products/services at the price those sellers demand.
