Is Universal Coverage enough?

A very good essay on single payer. Thanks to Joel Clemmer for finding it.
An excerpt-
"Most Americans believe lack of health insurance is a “serious problem” (NPR/KFF survey, Feb 2008). Current reform proposals claim to be the way forward. However, expanding our flawed system will not solve the serious problems we face – rising costs and lack of coverage (for uninsured and under insured). Unfortunately, having coverage in our system does not guarantee care. One-fourth of the insured go without needed care due to cost; three-fourths of individuals bankrupted by medical bills had insurance when they became ill. Is this a system worth perpetuating?
Reform efforts such as those proposed by HCAN and outlined by Senator Daschle maintain a central role for private insurance companies, and are thus doomed to fail because they cannot control costs."
