Personally, I don’t think Unions cause inequality among the rank and file members. They are all screwed collectively by their union leadership who are nothing more than crooks in suits.
If anything Unions serve to EQUATE humans to a Union define service grade which the union bosses dictate and from which collect their filthy lucre.
I disagree. I tried to learn every facet of my trade as a UA pipefitter and became very skilled while some of my “brothers” took the easy way out but still got the same pay and benefits as I did. And you can’t complain to anyone about it or fire them unless it was a serious breach in safety. All you could do is wait for the first layoffs to begin to get rid of these types.
