The Problems of Europe

From the Economist last week in a book review of the excellent Is the American Century Over by Joseph Nye:

"Europe is hardly a plausible challenger.  Though its economy and population are larger than America's, the old continent is stagnating.  In 1900 a quarter of the world's people were European; by 2060 that figure could be just 6%, and a third of them will be over 65."
