Why do so many Liberals blame insurance companies for the high cost of health care?

The insurance companies fight with health care providers to try to keep costs down because they obviously have an interest in paying less. Why do we hear so little about the crazy prices providers charge? It almost seems like many liberals think the insurance companies ARE the providers. Why has Obama chosen to demonize the insurance companies but not the providers that actually charge the insane prices in the first place?

The White House, Democrats, and MoveOn liberals are spreading health care sob stories to sell a government takeover. But there's one health care policy nightmare you won't hear the Obamas hyping. It's a tale of poor, minority patient-dumping in Chicago — with First Lady Michelle Obama's fingerprints all over it. Both Republican Sen. Charles Grassley of Iowa and Democrat Rep. Bobby Rush of Chicago have raised red flags about the outsourcing program, run by the University of Chicago Medical Center. The hospital has non-profit status and receives lucrative tax breaks in exchange for providing charity care. Yet, it spent a measly $10 million on charity care for the poor in fiscal 2007 when Mrs. Obama was employed there—1.3 percent of its total hospital expenses, according to an analysis performed for The Washington Post by the non-partisan Center for Tax and Budget Accountability. The figure is below the 2.1 percent average for nonprofit hospitals in surrounding Cook County. o_O http://www.washingtonpost.com/wp-dyn/con…
