Exactly true -- and we see that right wing propaganda still works its evil ...
The right wing very quickly in its attacks on Teachers and Post Office workers has demonized them and suggested they are people only worthy of America's hatred.
This is how the greedy among us work to project their own evils upon others.
The highest union representation the US ever had, I believe, was about 39%.
Today I think it's near 7% or less. And every means has been used by Elites/Capitalists to destroy unions and their members. Including using the Mafia to infiltrate unions and take over leadership, intimidate members, etal.
It has been an undying goal of moneyed interests to destroy the labor rights and justice that was won with so much struggle and even bloodshed
Americans have been taught to distrust and fear unions -- the organizing of labor -- while Capitalists are united and organized in a million different ways to work together in their own interests via hundreds of organizations and interconnecting company Boards. Not only in their own interests but very specifically against the interests and aims of democracy, equality for all, consumer rights, regulations on industry, safety in the workplace, taxes on the wealthy.
