Koch Brothers-style "libertarianism" is basically George Soros' vision of the world minus the welfare state. Both Soros and the Kochs want sovereign nation-states to become a thing of the past.
Very astute point, and to add to it, George Soros’ vision only includes the promise of a welfare state, not the reality. It’s not possible in any time frame worth thinking about to provide a welfare state for 7.5 billion people.
