Unions aside, there was the same butt-hurt regarding blue-collar oil field workers making 100k+. The New York Times ran endless articles complaining about the shale oil boom.
Non-elite flyover whites making good money seems to really upset a certain segment of the population. How dare they make a better living them me doing physical labor!
Most people have been taught to look down on blue-collar manual labor. Seeing them makes good money upsets them. Even the OP expressed his distaste for the oil-field workers.
