By class traitor I don't mean a fed or infiltrator. You don't have to go out of your way to denounce leftist ideas or stop the left. You just have to have class interests directly in conflict with workers and the poor. You can let your factory unionize, and take less money. But would you choose to be that factory owner if it meant your current situation improved significantly?
I don't know what I would choose because I have no hopes of owning capital. I would love to quit my job and be free to just own stuff and make money off it. But then I would have to reckon that with my beliefs. I guess you could just accept you can't be a leftist and volunteer for the wall should the day come.
This. You might not be able to stop the exploitation all the way down the supply chain, but you can at least collectivize what you have power over.
