US Healthcare "Best in the World"?

In talking with conservatives about healthcare and public policy, I hear repeatedly that the US has the "best healthcare in the world". My response is that is like saying Italy makes the best cars in the world. Italy does make Ferrari, Maserati and Lamborghini and they are the best cars in the world, but it certainly doesn't mean they have best car industry. America does have an out sized proportion of world class research hospitals but that doesn't mean America's healthcare industry is meeting Americans needs.
