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.
Third-worldism is kinda garbage. It paints with a huge brush all the irregularities of labor and compensation within a country, and serves mostly as a source of either guilt and despair for radicals.
Yes, there is a lot of wealth that companies extract from poor countries, and yes, a lot of it does end up in rich countries where sometimes it bumps up wages or keeps down prices in specific sectors, leading to a better quality of life for some people.
But a minimum-wage full-time worker making $18,000 a year is not "the global upper class", let alone "the global ally of the bourgeoisie".
