That is a myth perpetuated by business interests (and others with an agenda) in order to keep the costs of labor down and the demand for rental housing up. If I could, I would cheerfully send a never ending supply of surplus labor from California over to yer "holler."
You often cite the pay disparity between UPS and XG as a reason why XG cannot attract and retain drivers.
It is my experiences and those of people I have known that UPS does not roll out a red carpet for people who wish to work there.
An interview at UPS is not unlike the experience I imagine of a filthy, drunken, unwashed beggar propositioning a supermodel for a quickie behind a vermin infested, overflowing, leaking dumpster.
There you go again. Believing a 1%er CEO when he cries about a "labor shortage".
