Agree with what? Where are your numbers? Most of the accusations of the current system I'm seeing have two things in common:

-- There is damn little in the way of data on the claim, or the data actually refutes it. "The system is broken" doesn't stand up when actual numbers are consulted.

-- As far as overruling doctors or denying claims, there is no reason to believe that a state-run health care system wouldn't do the same thing or worse.

Look at this (boldface mine):

The AMA evaluated claims for more than 5 million electronically billed claims to Medicare and seven large private national insurance companies: Aetna, Anthem Blue Cross Blue Shield, CIGNA, Coventry Health Care, Health Net, Humana and United Healthcare.

Medicare was the most likely to deny any part of a claim, with a 6.9 percent rate. Aetna was a close second at 6.8 percent while the others ranged from 2.7 percent to 4.6 percent.

Coventry Health had the fastest median turnaround between receiving a claim and responding, at four days, according to the AMA. Medicare and CIGNA took a median 14 days; Humana and Aetna, 13 days; Health Net, 11; United Healthcare, 10 and Anthem, seven.

Most of the "facts" in this controversy float unsupported in midair, repeated endlessly without sources. It doesn't take much work to prove them wrong, and continuing to repeat them more loudly changes nothing.
