This is what people mean when they say there is no ethical consumption in capitalism. Yes, you are a leech, but only because the system has forced you into it. In a different system, neither you nor the Ukrainian family would have housing insecurity.
I don’t say this to judge you, btw, I think we should applaud every landlord who keeps rent low. Just pointing out that it’s impossible to both “keep your hands clean” and “get ahead” in capitalism.
For all the people talking about Vaush and Hasan and their controversies, realize that there are other folks out there where you can learn about theory without the Twitch brainrot. The Revolutionary Left podcast is my personal favorite.
