"> It's possible that in the US they simply spend more money on useless things, or do more screenings with better technology These are both components to saying that the health care system is more expensive in the US."

"This implies that differences in social services and urban design have an impact on healthcare spending." How does it imply that? More social services would stop people from overeating? Do you have a citation for that?
