He has said many times he believes single payer (or as the right wing has portrayed it "bureaucratic national socialist nazi eugenics government takeover rationing death panels") is the best system IF we were starting from scratch. Obama is a political realist and knows that a radical restructuring and elimination of an entire industry (private health insurance) would be too disruptive and politically impossible. He believes in achievable evolution, rather than idealistic revolution. How insurance is paid, whether public or private is not the only issue (read The Cost Conundrum:

I agree with Obama that we need to find more efficient models of delivery to lower costs, such as the mayo/cleveland clinic etc..where doctors are on salary and share info rather than independent contractors with income based on fee for service. We also need to have a public health insurance option to compete with the out of control private insurance industry, have a larger pool to negotiate for lower costs of drugs and services, and to cover the uninsured (who we are paying for at inflated costs anyway). And we need to have, as he's said, better preventative care and access for regular checkups to catch problems before they require expensive interventions. He's also talked about unnecessary subsidies to the private health insurers.
Another thing that comes to mind, and related to prevention, is personal responsibility. This debate should not just be about the system we create for health care, but about how many in our country live their lives locked to computers, driving and not walking, eating too much, and not exercising regularly. I grew up in the 60's and we had President Kennedy's physical fitness initiatives in our elementary school. As a result, I learned early on to exercise and take care of my body. Think of the skyrocketing rates of childhood obesity and diabetes now without childhood phys-ed being emphasized as a public health concern. Think of the enormous long term costs associated with neglecting this aspect of public health. I think Obama could easily resurrect these initiatives and save us health care costs in the long run.
I would also like to see Naturopathic and Alternative Medicine be covered by insurance. I often find their services more effective and MUCH less expensive. With this provision, the traditional medical establishment would have competition for health services, further lowering costs and expanding consumer choice.
Another thing Obama hasn't talked about yet and i wish he would add to this debate is the corporate food industry's use of chemicals that are addictive and making people sick and obese. The farm subsidy of corn has caused the use of high fructose corn sweetener as a cheap additive that has very detrimental effect on health. I'm guessing he realizes that taking on the corporate food industry at the same time as the corporate health industry is political suicide. Smart guy. One step at a time....
