Suzy...how many unemployed Appalachian coal miners do you think are going to load up the pick up truck and the family and move to California's Central Valley with their Degree from the Trump School of Nuts only to find out they have machines that shake the walnuts and almonds out of the trees and on to a tarpaulin?

What's that leave...vegetable harvesting as the former workers in those "fields" disappear?

"retraining programs"...as you noted......."for those who want them"!
