I don't have an objective mechanism of evaluating whether or not a system actually promotes health. The issue is exemplified in comparing Japan's health system to the US; do you compare averages of everybody, or just the averages of, say, Japanese-descended people living in the US?

Somebody whose lineage traces back to Japan does as well in the US as in Japan, is the issue. Comparing the two health systems of the basis of population health ignores that the healthcare system may represent only a minority contribution to the health of the population. It's not that I don't think it's an important criteria, it's that I don't believe I have any mechanism of reliably measuring it; to the extent that it can be measured, I judge it being measured in the "Innovation" column, which produces in successes a better healthcare system. (That is, I believe the metric of success in promoting health is better measured at the rate of change in the system's ability to promote health.)

I do agree that taxation is orthogonal to healthcare, which is why I'd prefer a national healthcare system with private options to the healthcare bill we got, which directly violated my #1 criteria.
