Back in the good old days (ten years ago), rich countries accounted for the majority of the world's GDP, as has been the good and proper economic custom since the times of Pontius Pilate. Not any more!
Look at these fucking economic charts from the OECD. In 2000, OECD members (more affluent countries) had a healthy majority of the world's GDP. Look at where we stand now: just barely clinging to a tiny advantage over the unwashed hordes. And by 2030: total domination by the poors. Goodbye, sweet capitalism.
