The typical labor union is dead. The initial organization of unions was all American to protect the American worker and to fight for American worker rights. The globalist,open borders,pro-illegal alien union whores are not very transparent. They make connecting dots much easier in understanding why the GOP sucks. I think they have strayed and are imploding EXCEPT for the GD government and teacher unions which are obscene.
The hierarchy of the major unions are just a peevish lot, storming and raging at Trump for painting a picture of prosperity and plenty. No union in the history of the United States has EVER been on the side of general prosperity, because once the magic of reward for productivity on the job passes its aura over the individual worker, there is no longer any obvious need for unions.
Scarcity is the stock that the left uses to gain its objectives, whether it is because of a genuine bottleneck somewhere in the supply chain, or because of artificial scarcities created by overregulation or abusive taxation. Unblocking the bottlenecks, or reducing the artificial restrictions on the operation of the rewards for productivity (usually registered as higher wages and/or take-home pay for the individual), causes these people to question the need for a labor union for any purpose.
