Honest question as someone who prefers single payer but acknowledged it's not a silver bullet: how much of the costs are nurses and doctors vs. admin? It seems to me there's a lot of overhead in passing the bills around to get paid. I just had my appendix out last year and got billed 8 times by 8 different firms, each with payment portals, call centers, billing providers, etc. I assume there's a lot of inefficiency internally too.
