China and India. Rarely has the economic ascent of two still relatively poor nations been watched with such a mixture of awe, opportunism, and trepidation. The postwar era witnessed economic miracles in Japan and South Korea. But neither was populous enough to power worldwide growth or change the game in a complete spectrum of industries. China and India, by contrast, possess the weight and dynamism to transform the 21st-century global economy. The closest parallel to their emergence is the saga of 19th-century America, a huge continental economy with a young, driven workforce that grabbed the lead in agriculture, apparel, and the high technologies of the era, such as steam engines, the telegraph, and electric lights.
But in a way, even America's rise falls short in comparison to what's happening now. Never has the world seen the simultaneous, sustained takeoffs of two nations that together account for one-third of the planet's population. For the past two decades, China has been growing at an astounding 9.5% a year, and India by 6%. Given their young populations, high savings, and the sheer amount of catching up they still have to do, most economists figure China and India possess the fundamentals to keep growing in the 7%-to-8% range for decades.
Barring cataclysm, within three decades India should have vaulted over Germany as the world's third-biggest economy. By mid-century, China should have overtaken the U.S. as No. 1. By then, China and India could account for half of global output.
