I could be wrong about this but I think non-union workers became jealous of union workers getting paid more for the same work and started voting against unions...and thus we got "Right To Work" laws.
Politics hasn't necessarily moved right, it has moved to stupid.

Also I think everyone here realizes we have entered into another "Gilded Age" and something is going to have to stop it. This is typically the job of the "left" and things being what they are, it's going to fall on the Democratic Party to actually become the left after a long comfortable run in the middle.
