That's an incorrect measure to look at though. Per capita social expenditure is highly dependent on the welfare structure of a country. There are developed countries (notably the Arab welfare states - for their citizens only!) which get away with a much lower expenditure even adjusted for PPP, simply because the government directly handles the provision of a lot of essential services such as education and healthcare. The US Medicare system is structured in a way to inflate its own costs.
