by creating another middleman in healthcare. This was first proposed by Jim Clark's Healtheon. "We want to empower the doctors and the patients and get all the other assholes out of the way." … "Except for us. One asshole in the middle." — The New New Thing, Michael Lewis.
The reason we spend so much is that public healthcare is a public good and private companies aren't good at managing public goods. They're good at making money which is a different purpose (which has probably served most people reading this very well). We need Single Payer. Indeed we have Single Payer in Medicare and TriCare and other areas. It works pretty well. We need to eliminate middlemen in healthcare by actually eliminating rent seeking middlemen in healthcare.
