Healthcare Costs In the U.S.

This is a subject that I want to delve into more deeply in the future. I want to understand why healthcare costs are so high in the U.S. This website is a good place to start. Here's the money quote:

All-payer rate setting is a system in which insurers band together to negotiate rates collectively. We the people could shift our current “ObamaCare” based system to a single payer system with all-payer rate setting. This one move could take the power away from for-profit health care providers and put it in the hands of the American people.

You don't even need a single-payer system. You just need an all-player rate setting and even that would bring costs down.

Also, see this article, where the author argues that single payer wouldn't be enough to bring down health care costs. She doesn't discuss pharmaceuticals though.
