The first one is better (IMO).
Ocasio-Cortez has so far flailed pretty badly on the “how would you pay for all this stuff?” question. She seems not to grasp that you can’t do so just by reallocating the Navy’s budget (though that would help). In the real world, you finance soft-socialist guarantees with a level of tax revenue and borrowing you can only sustain through capitalist innovation, competition, efficiency, trade, and growth. That’s the lesson of the Nordic social democracies.
The theoretical promise of socialism, like the promise of the Bismarckian welfare state that was developed as a liberal alternative to it, is that it fortifies the individual by insulating him from bearing the full weight of social and economic forces beyond his control. This is hardly an exclusively progressive or left-wing idea: F. A. Hayek’s argument for various kinds of social insurance and welfare plans was based on much the same thinking, with the state “providing for those common hazards of life against which few can make adequate provision.”
