Thanks for being open-minded!
I might say that capitalism does work, but only for the ruling class (business owners) and those they can rope into doing their anti-worker dirty work. The system isn't broken and need fixing, it's working exactly how they want it to and it must be destroyed.
Being vaguely socialist is 100% cool btw. No need to get too deep into labels. The most helpful thing is to be class conscious and be active in your community in a way that's cognizant of that. Helping people get better wages, win unions, support politicians antithetical to capital (they're very rare and nobody in the squad would count), support strikes, support social housing, oppose war that your country supports, and so on. Never supporting cops in capitalist countries. Diving deep into left theory is handy for doing those things better and having clear eyes about what is coming next, but it's less important than doing some of these clearly good anti-capitalist things. It can also help you choose a group to organize with, as some groups are do-nothing orgs.
Also nothing wrong with wanting to live in a smaller community or even a reclusive life. Alienated city life is an imposition that violates the connection and community most people want to have. Folks can't plant roots long enough to know their neighbors, let alone create a community. That's a consequence of real estate, rent, and unemployment, a whole other can of worms.
There's a recent book you might enjoy called The Dawn of Everything. It's co-written by David Graeber, who had anarchist leanings but respected Marxist thought. It has many examples of societies defining and redefining themselves relative to material conditions snd relative to one another.
