I find it ironic that the government spends so much money subsidizing high fructose corn syrup, and then spends even more treating the health problems that result from it. If we didn't have an agricultural system that makes unhealthy food cheap and healthy food expensive, perhaps we wouldn't have quite so many obesity-related illnesses.
Same thing with parking lots and interstates being subsidized while dense urban development (walkable/bikeable neighborhoods) is not. Cars kill a lot of people outright through accidents, and then indirectly through people becoming couch potatoes.
Usually by the time people come under care of the health care, the battle's already been lost. Acute, lifesaving interventions on otherwise healthy people aren't all that expensive. Chronic conditions caused by 40 years of neglect are. I'm curious if we'd get both the cheaper health care and the longer life expectancy of European countries if our cities were laid out like theirs and our agricultural system didn't dump massive amounts of subsidies on the corn industry.
