Of course there are ways in which single-payer might be better. Whether the strengths outweigh the weaknesses is an argument best left for another day.
Today I’ll just finish by reiterating the point I made at the outset: The financing is impossible, in part because the politics is impossible. And the politics is impossible in part because the financial hit would be too big. Single-payer would have to be paid for at the extremely high prices that Americans pay, not the lower European prices that we’d rather have. And when you look at the taxes needed to finance a government takeover, you quickly realize that most people just aren’t willing to pay the price.
