Competition

Off-topic from the usual fare here, but Ezra Klein looks at John Edwards' health care proposal and notes this:

Where the Edwards' plan takes a big step forward is in mandating, along with the private options, that HMs offer "at least one plan [that] would be a public program based upon Medicare." And the intent is explicit: "Health Markets will offer a choice between private insurers and a public insurance plan modeled after Medicare, but separate and apart from it. Families and individuals will choose the plan that works best for them. This American solution will reward the sector that offers the best care at the best price. Over time, the system may evolve toward a single-payer approach if individuals and businesses prefer the public plan."

In other words, the public sector will finally be allowed to compete with the private sector, and consumers will be able to decide which style they prefer. For Democrats, this is a significant step forward.

I really agree with this assessment, but since I don't study this to the extent that Ezra and others do, I'm curious what others see as the drawbacks.
