“””””In my neck of the woods you have to really look to find a white guy doing manual labor like yard work, painting, etc.”””””
Because they were driven out of that work, and there is no level where it stops, picking vegetables turns to yard work, turns to painting, turns to electrical, turns to machinist.
Go to any area in America where it is still all white and you will see that all the work is still being done by local whites, your gardener is white, your busboy is white, your roofer is white.
Where I live Hispanics are 10% of the population and perform virtually all of the manual labor, yard work, house cleaning, private child care, construction, hotel housekeeping, car wash people, crop picking, etc. I presume most of them are here illegally. Are you saying that American citizens would do those jobs if they were available? I seriously doubt that that would happen.
