This is an important graph. The share of national income going to the richest 10 percent was lowest (and share to lower 90 percent highest) when union membership was at its highest. As unions have weakened, inequality has widened. It's not about economics. It's about power.
@rbreich When was the last time the Democrats passed a federal pro union law?

@rbreich @Gorba
I had to go look for that, and have you considered the PRO act? en.wikipedia.org/wiki/Protecti… The only time anything related to it passes, it's supported by Dems and opposed by Repubs.
Protecting the Right to Organize Act - Wikipedia

@chiasm @rbreich Yes, and it usually fails by one or two votes and the Dems go “oh well we tried nothing we can do” or it gets delayed until the Dems lose the majority and the GOP stop it, weird how it always ends up that way.
