Those were thanks to labor movements, not unions. They are not the same thing, labor movements happens thanks to Democracy. Democracy is crucial, I agree, it lets groups organize, protest and fix problems with how society works. But what we call unions today are not that.
I'm all for labor engaging in politics, but they can do that without paying union dues for working at a company. The problem USA's workers face today isn't lack of unions, it is lack of proper representation in their democracy.
