"Best of all, the Obama plan contains the same feature that makes the Edwards plan superior to, say, the Schwarzenegger proposal in California: it lets people choose between private plans and buying into a Medicare-type plan offered by the government.
Since Medicare has much lower overhead costs than private insurers, this competition would force the insurance industry to cut costs — making our health-care system more efficient. And if private insurers couldn’t or wouldn’t cut costs enough, the system would evolve into Medicare for all, which is actually the best solution. "
