For a more actionable take on how (from a policy perspective) the US might get to a progressive health insurance system, I highly recommend this lecture from Ian Shapiro: https://www.youtube.com/watch?v=kqm8T_FNnog https://www.youtube.com/watch?v=kqm8T_FNnog. The series is somewhat lengthy, but he takes the important step of enumerating all of the challenges and political/economic/cultural forces that have stymied attempts so far, then proposes a very concrete and incremental path forward that should minimize the aforementioned pitfalls. Given how much we like to argue about what "should" be done in legislative politics on these online fora, I found his breakdown of why these "shoulds" often don't materialize to be very insightful.
