Why does Obama only want to talk about health insurance instead of talking about the prices providers charge?

The prices health care providers charge are ridiculously high. Why isn't that a major topic? Obama stokes up all of this hatred towards the insurance companies when the fact is they are helping to keep prices down by demanding & getting discounts from the providers. Why doesn't Obama want to reform the whole health care industry instead of just picking on one facet of it?

He doesn't understand how insurance works..
