To be fair a couple of states cracked down hard on illegal immigrants and millions of dollars of crops rotted cause there was no one there to pick em. The states reversed course pretty fast.
Americans are pretty lazy at this point, and I speak as an American.
This is also true, but that true across most industry in America at this point.
If pay is even across the board than why would one person want to toil in the sun vs sit on thier bum and deal with angry customers. Most pick the angry customers...
Even when the more manual labor jobs do pay well, a ton of people quit after a day or two, granted they're usually younger people who didn't realize what the job would entail.
