Q. But those 3 billion [in China, Russia, India and Brazil] have less money and less GDP. How will that drive the world economy?

A. These people don't have the roads, the airports, the infrastructure - and the building of these creates big demand for industrial raw materials and energy in all forms. In a nutshell, these foreign countries place a high priority on growth. The broad pattern is they're more concerned about maintaining growth than other factors, be it pollution or inflation.
