I watched this video and thought of something.
https://www.youtube.com/watch?v=EO4Ko-v-q0gSanders begins by saying he'd like the United States to be like Scandinavian countries like Sweden, with free education, health care, etc. O'Reilly counters, at about the 1:00, saying that isn't feasible since countries like Sweden are smaller and can thus afford the HC and schooling.
Is this true? Is the reason free schooling, HC, etc. work in those countries but not the U.S. is because the U.S. is larger?
