It ignores the 30 point gap in obesity - 6% for Singapore, 36% for the US - which is obviously a big contributor to the US healthcare cost problem. 36% obesity is an extreme elephant on the table for costs. I would be surprised if the US couldn't shave 1/5 off its healthcare costs with a 22% obesity rate (comparable to Germany, Brazil, Poland, France, Sweden, Netherlands, Finland, Norway, Austria, Spain, Russia, etc). Singapore vs Japan and South Korea is a more interesting comparison (similarly very low obesity rates) between costs in developed health care systems, if you wanted to see which worked better. Japan for example has a spiraling healthcare cost problem related to its aging population.
