I did. I wrote several papers on it. The OECD spends far less for better outcomes than the US with lower slope of growth. And the growth is in large part due to demographic changes as populations age. Changes in demographics shouldn't be used to say health care doesn't answer cant work. Its ratios of spending across a population as some pay in when they are healthy and some consume as they age. Change the ratio and cost as a ratio also changes.
