Well, we’ve never had socialism in a developed country so there’s no direct evidence for it.
But it makes sense. A country with a social democratic government and institutions is closer to socialism. It’s a smaller jump from one to the other, than it would be under any other government.
What?
No, AOC is not going to bring about socialism. That’s my point. Expecting that of her, and being disappointed when she doesn’t deliver, is ludicrous. She’s not going to just go in and break things. She’ll get booted next term and be replaced by a neoliberal who’ll just make things worse. Her job is to do as much good for as many people as possible by working within the system.
