From Scott Sumner at TheMoneyIllusion:

Obamacare … was going to improve health by eliminating the problem of people … without health insurance. The group that is far and away the least likely to have health insurance is Hispanics. They also have an obesity problem. And yet their life expectancy is 81.8, compared to 79.0 for whites. Why? I have no idea. But … it suggests that health insurance isn’t the issue, something else is going on.
