I’m speaking from an anglocene perspective I admit.
The “left” in the UK and US has had power. But they didn’t contradict right wing economic policy from the 80s when they had the chance.
We’ll see what they do next time they get a chance but looking at the UK we haven’t had a left wing government that would help since the 70s and it’s hard to start a conversation about who to vote for by talking about things that happened before someone was born.
The track record of Labour in the UK and the Democrats in the US is not good enough in the living memory of the voters they want to turn out for them.
