Dems used to be pro labor, Repubs used to be pro business (on balance, but kind of served both when it made sense).
In the ‘80s Dems saw being default pro business was more lucrative and jumped ship.
Now both parties play both hands and workers get shafted.
Oh but the Dems are pro workers! No, they are not. They pretend they are. The only ones who are pro worker also sold out (Bernie) and went globalist —Compare his positions in the 80s vs now.
