I fear they will just start moving North.
They are already here in the north. You will find them in the darndest places if you know where to look. From the greenhouses, to the garden centers, to the plumber you may have hired last week to snake out the drain, to the McDonald’s you bought lunch at last week, or your neighbor’s babysitter. Don’t kid yourself and don’t fool yourself.
It took me 4 attempts to find a contractor that was “All American.” I am still looking for that plumber who is “All American.” I make no bones about it.
