To be honest, I don't think most people understand what the definitions of capitalism or communism or socialism are any more.
And it cuts both ways, 99% of Lemmy is like Mirror Universe Fox News, where if they see something bad, it's capitalism's fault. Someone crashed their car? Capitalism did it. Someone got sick? Capitalism. Fox viewers blame everything on "socialism" and have no idea what it means, either. For Lemmy it seems to be just any system that exists on Earth that isn't a utopia.
Case in point: capitalism isn't actually corporate feudalism. That's not in any way what defines capitalism as an economic system.
Kids, please - humans are shit to each other under every system ever imagined. And they would be shit to each other under any new system we can imagine in the future. As is evidenced by how people are shit to each other and complain about their lives in every other country on Earth. No where is unique in that no one complains about being there.
