SICKO Billing - Single Payor System Would NOT Impact Quality of Care?

As a Professional Mdical Biller, I continuously seek information on the possible impact of a change in our health care system.
The reason that I do this, is because I survive on the process as it exists today.
Private practice owners generally do not have the resources or the money to support the overhead in keeping medical billing in-house. They seek an outsourced solution, like ME to process electronic medical claims on their behalf.
I am convinced that a single payor system would NOT improve anything BUT the paperwork currently required. That is it. It would not impact the quality of care at all.
So, with that said, perhaps health care system in the US shouldn't change all that much?
What I would like to see change are the numbers of people that lack health coverage go away entirely.
Every person deserves health insurance and all should have it for proper medical care.

I found this quote at http://whynow.dumka.us/2007/07/02/more-on-the-sicko-issue/

"Paperwork is a major cost of the American health care system that would be radically cut by a single payer system, and would have no impact at all on the quality of care. This is something that the insurance companies could have done decades ago, but chose not to, and just made it worse. Confusing billing procedures delays payouts, and that is one of the reasons they do it, no matter what they tell you."

And, I agree.
