My parents are petty landlords too. They're also exploited workers as well. They simultaneously occupy both classes and it's a factor that prevents them from seeing things clearly. And worse, they don't actually make returns on their investments and havent since they started renting out property years ago. They should see how rigged things are by now but "temporary embarassed millionaires" and all that. I get your frustration.
But also, realize how normalized and propagandized it is for everyone to be a landlord or entrepreneur now. In that sense your parents and my parents are victims of that. Like you said, they're just trying to have an easier life and aren't heady about this political stuff like we are.
While there is an exploited class and an exploiting class, it's not necessarily indicative of where someone's ultimate interests lie. Plenty of petty bourgeois circumstancially have more in common with workers and plenty of labor aristocrats have an individual stake in preserving capitalism.
Let ideology be a guide for you, but don't treat it like a cult. If you let it dictate who you love or who you're friends with, you're gonna be pretty miserable and ultimately you'll find yourself creating more divisions, not healing them.
Precisely. I personally think we can still remain Leninists while reevaluating the relevance of vanguardism. If someone disagrees with that, I welcome the counterpoint.
