Nice collection of graphs, but I want to add to the graph about the Public spending, that one should add at least a significant part of the private health care spending in the USA as 'public spending' for most intentions, even if it is private, because as well in the other countries people would spend a part of their income on health care if it would not be public.
Taking into account, that health care spending as a part of the GDP has increased in the last years in most countries, this would likely even lead to a stronger increase of public spending in the US making the strength of the US post 'New Economy' recreation even less compelling.
And of course in the employment picture employment-share of work-age population might be more useful. Why should a country with a shrinking population make as much new jobs like a country with a growing population?
