The GOP is the party of our oligarchs (so is the Democrat party, of course, they just serve as an emotional relief valve for the working class—sometimes on sometimes off—while the GOP is always off), and they will resist every effort to democratize the economy. Since the general population is taking political democracy for granted (to their peril) and extending their recent efforts to extend democracy to the economy, our oligarchs are feeling threatened. It's all this talk of "socialism" among our youth, the recent surge in strike actions, etc. you see.
But I'm not saying anything new, am I? Remember the popular "golden rule": those who have the gold make the rules.
