It's hard to envision such a drastic (and labor friendly) change passing in a climate where the much milder PRO Act couldn't get passed when an allegedly labor friendly party and leader controlled both houses and the presidency.

The path to winning such changes - whether through changing the law with the political process or simply forcing employers to bargain with industry wide strikes - requires much more powerful labor movement. The path to that is simply to build whatever power is possible. Right now the labor movement just trying to get organizing and union membership on the upswing, and I think that's the necessary step from where we are today.
