Being busboys and dishwashers
How strange. When I was in high school in the late 70s those very jobs provided me with spending money, and I'm not Mexican. Neither were any of the dozens of other high schoolers who worked the same jobs alongside me. As best I can tell, none of us ever thought ourselves "demeaned", "exploited", or thought that clearing away and washing dishes was a job that was beneath us.
So what changed?
What changed is that lawnmowers can only be run by illegals; were it not for mowing lawns in the neighborhood, I would never have been able to afford my college textbooks. Can't bus tables, because one has to speak fluent Spanish to speak to the rest of the kitchen staff. Make beds in a motel? Oh, no, there's an illegal there doing the job.
These aren't jobs that Americans won't do, these are jobs that have been stolen from our children.
So what changed?..... Society changed
How many kids do you know now a days that have dishwashing jobs after school? or mow lawns and cut trees for extra money? I know the kids that bag groceries at my local supermarkets are so slow I end up bagging my items myself.
