I was maybe underemphasizing the labor costs - it's a real contribution. But you are right that everything is more expensive, and it's pretty interconnected. Big contributors: fee for service incentives, administration overhead, end of life care, inefficiencies due to fragmentation and licensing, insurance inefficiency (not the profit margin, but the tracking/coding level of detail), over subscription of expensive (e.g. capital heavy) procedures, pharmaceutical costs.

I'm reminded of https://slatestarcodex.com/2017/02/09/considerations-on-cost... when these discussions come up.
