david, your basic argument is that health care does not function the way most markets function. >> right. well, we haven't taken advantage of the things that most markets bring to most industries. we haven't taken advantage of competition and empowered consumers and differentiation and services and quality and we stripped out of health care. >> and give an example. you use lasik care of how a procedure, sort of medical procedure not covered by insurance works in a more marketized situation. >> if we look at any of the parts of health care that are outside of the insurance system. so, lasik and other eye care and dental, it's very price competitive and also very quality and safety competitive. where you see people competing against each other on safety and on quality. we don't have that in main stream health care because we've got the wrong customer. we have big insurers or
