@sim What the US supposedly have for a "left" they call "liberal". Enough said. But I will continue anyway just to be clear. 😅
They do not have a proper social democratic party because their population is trained to be afraid of collective solutions even where they make sense.
Europe is suffering from neoliberalism since the 90s, but the US is where it came from. They've had Reaganomics, deregulation and trickle-down economy since the 80s, and they have an ongoing red scare since the 50s, which only softened a bit in the 60s, and which is preventing them from implementing a regulated mixed market.
I read Obama's book when he became President, and I was shocked by how right-wing it was compared to European politics.
