My father-in-law is a retired UAW member who is STILL stupid enough to believe his union’s spin that “less than 1%” of member dues are spent on political activities.
Having worked in UAW represented shops for more that 40 years, I can attest that they are very effective at brainwashing most of their serfs. And since the union has a big influence in who gets hired as new employees, they are often spawn of the current serfs.
