My theory is unions thrive when there's a labor shortage, so workers will get paid more just because there's a labor shortage, decreasing inequality. If there's a labor glut, the union model falls over because it can't maintain its monopoly, and executives pat themselves on the back for lowering production costs, even though it was mostly driven by the macro environment.
