A public option, Shelby added, would "destroy the marketplace for health care."

But the notion that most American consumers enjoy anything like a competitive marketplace for health care is flatly false. And a study issued last month by a pro-reform group makes that strikingly clear.

The report, released by Health Care for America Now (HCAN), uses data compiled by the American Medical Association to show that 94 percent of the country's insurance markets are defined as "highly concentrated," according to Justice Department guidelines. Predictably, that's led to skyrocketing costs for patients, and monster profits for the big health insurers. Premiums have gone up over the past six years by more than 87 percent, on average, while profits at ten of the largest publicly traded health insurance companies rose 428 percent from 2000 to 2007.

Far from healthy market competition, HCAN describes the situation as "a market failure where a small number of large companies use their concentrated power to control premium levels, benefit packages, and provider payments in the markets they dominate."

So extreme is the level of consolidation, in fact, that one former top Federal Trade Commission official working with HCAN has sent a letter to the Justice Department's Antitrust Division, asking for an investigation into the health insurance marketplace.
