There are plenty of "white folks" who are happy to do menial labor. You don't hear about them because they don't make as big of a splash in newspapers.
For example, Amish, Hutterites and fundamentalist Christians do all kinds of menial jobs in farming, contracting, maid services and manufacturing. They are legal, they speak English, they aren't trying to take over the Southwest to create a Hispanic state and they don't clutter up the criminal justice system.
We need more of them. But since they have about six kids per family and their numbers have increased by a factor of 36 in the last century, we should have enough after we kick out the illegals.
I like that, Amish wine growers.
Generally speaking, menial labor goes to the lowest wage earners.
