Today’s social democracy falls apart on the contradiction between advocating nearly unlimited government largess and nearly unlimited immigration. “Abolish ICE” is a proper rallying cry for hard-core libertarians and Davos globalists, not democratic socialists or social democrats. A federal job guarantee is an intriguing idea — assuming the jobs are for some defined “us” that doesn’t include every immigrant, asylum-seeker or undocumented worker.

Trump gets this, as does the far right in Europe, which is why they attract such powerful working-class support. Want to preserve the welfare state? Build a wall — or, in Europe’s case, reinstate border controls. Want more immigrants and amnesty? Lower the minimum wage and abolish the closed shop.

But please choose. It’s one or the other.
