Honestly the realization that capitalism is the root cause of our current systemic evils, and finding a good organization to fight back against it with did me a world of good mentally. Way better than agonizing over every tiny decision I made because I’d been tricked into thinking that climate change was my individual fault and responsibility to fix.
What organisation is that?
I personally joined Socialist Alternative. I think we do good work, lots of focus on movement-based politics, workplace organizing, that sort of thing. It was before I joined, but we won the first $15/hour minimum wage in the US, which I think is a pretty big achievement. Plus we have good, principled stances on the Russian and Chinese ruling classes, (just because the US ruling class is bad does not mean the ruling classes that oppose them are good, or bastions of left-politics) which is unfortunately a pretty divisive issue on the left.
