Ezra posts the above chart on the connection between income and life expectancy. He argues elsewhere:

One of the ironies of America is that we've become really, really rich, but that's also allowed us to disregard an enormous amount of inefficiency and waste in our midst. Letting people retire at 65 rather than 70 costs money, but it at least serves a distinct purpose. Spending twice as much as other countries for health care without getting better results doesn't, and bearing half the world's defense spending on our shoulders is a questionable priority, as well. I'd be a lot more open to raising the Social Security age if there wasn't so much obvious fat to cut first.
