At the risk of sounding like a class reductionist (I'm not), even things like racism and LGBTphobia are exacerbated by this, because the only reason we don't just eat those ten guys is we're always hating each other. The reason there's so much racism in the US, for example, has a lot to do with slavery -- and guess who benefitted from slavery? Guess who benefitted from the genocide against Native Americans? Who benefits most from calling refugees and undocumented workers "illegal immigrants"?
It's not me. If you're reading this, it's probably not you. It hurts us. It hurts our communities, while these ten people keep brainwashing us into actually defending them and their system while hating each other.
