That's great for marginal costs. What about fixed costs?

The lobby needs to be mopped. The parking lot needs light. The lawn probably should be kept from turning into a forest. The heat should run in winter, and the cooing in summer.

You're missing the point here. The idea is that for you to have an a chest x-ray done, or an appendectomy, or a hip-replacement, is priced at the same rate as if I have the same work done. That they're not charging my insurance company X, while charging your insurance company Y, and Medicare Z, for the same service.
