"...Milton Friedman is wrong. It’s not incompatible with a welfare state; it’s incompatible with a welfare state that doesn’t differentiate between people within its territory. Singapore manages to maintain an enormously high level of benefits for its citizens with massive mobility. Kuwait has one of the highest immigrant populations in the world, and you can’t ask for a more cradle-to-grave welfare state than what Kuwait gives its citizens. So it’s obviously possible to maintain whatever level of welfare state you want and have whatever level of labor mobility you want, as long as you’re willing to separate the issues..."
