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 is the fundamental contradiction. Modern capitalism forces you to work against your fellow proles if you want any chance of even living a normal fucking life. I don't blame anyone for trying to survive within a system where they have no choice.
The solution is collectivism. Do what you can to organise, ally with others, and actually change that system so it no longer pushes people into these situations.
Up to the point of being work-free, I can kinda forgive. If you're landlord or a fuckin' factory owner, just sell your goddamn capital to some class-conscious workers and live your life off that money or there will be stabs
