"Please explain how the living standard in the US can have improved if real wages have fallen." I cannot believe the ignorance of Ycombinator at times. http://en.wikipedia.org/wiki/List_of_countries_by_GDP_(PPP) http://www.google.com/publicdata/explore?ds=d5bncppjof8f9_&#... Keep calm. Carry on.
I can't believe it either. Some even believe in the economists' equivalent of a cosmological constant: PPP, which when employed miraculously turns Louisiana into a richer place than Switzerland.

In regards to GDP by PPP:
"Comparisons of national wealth are also frequently made on the basis of nominal GDP, which does not reflect differences in the cost of living in different countries (See List of countries by GDP (nominal) per capita). Using a PPP basis is arguably more useful when comparing generalized differences in living standards on the whole between nations because PPP takes into account the relative cost of living and the inflation rates of the countries, rather than using just exchange rates which may distort the real differences in income."
