I think an even better statistic would be the following (GPD per hours worked): http://en.wikipedia.org/wiki/List_of_countries_by_GDP_(PPP)_... The differences are remarkable. However the comparison is not entirely fair with countries like Norway resting at the top. Norway derives a large part of its GDP from industries which are not very labor heavy but contribute heavily to GDP (Norway's economy is >50% based on petrochemicals).
