I respectfully disagree with your position on unions. As a necessary evil they prevent (to some extent) extreme abuse of employees that was rampant in the U.S. until unions came along. All this (like so many other things) is recorded in history in great detail. Governments do not prevent this type of abuse. Witness pre-union America, China Today... Mexico... Does GNP or labor supply and demand protect them?
I don't belong to a union today but when young I witnessed both union and non union shop conditions. Even non-union shops in the U.S. benefit because the union is waiting outside the door.
