US obesity rate: 36% Swedish obesity rate: 18%

US life expectancy: 79 years Sweden life expectancy: 81 years

It is falsifiable. When I talk about culture I'm talking about things like smoking rates, obesity rates, etc. These things are totally unrelated to whether or not you pay a copay to go to a doctor. If you think our relative life expectancy has nothing to do with our obesity rates, then I'm sorry but you just don't need to be making statements about healthcare at all.
