i read an interesting take in that the union's undoing is the fact that they are so quick to agree to wage cuts but fight being able to collectively bargain those wages quickly away. most people see little benefit to joining a union that quickly folds when it comes to wage fights.

people often respect those they disagree with simply because they have a backbone. not standing up for your core principles will be the undoing of not just unions but the democratic party as well. why vote for democrats when they will not put up any resistance or agree with those who oppose them.
