Data point of n=1: I think this effort by NY is exactly where the experiment of single-payer health care in the United States should occur, as per the 10th Amendment. According to Third Way[1], (which advocates for federal-level universal healthcare), three other states which have tried single-payer health care have ended up discontinuing their programs: Colorado, Massachusetts, and Vermont. Perhaps New York has identified where those states have failed and its proposal will address those shortcomings.
