With India Shining until recently, the urge to migrate had weakened somewhat. The downturn in the US will weaken it further and enhance the domestic pool of talent with returnees.
"With the economic downturn, my guess is that we'll have over 100,000 Indians and as many Chinese return home over the next three-five years," says Wadhwa. "This flood of western educated and skilled talent will greatly boost the economies of India and China and strengthen their competitiveness.
...... Until recently, America has been the prime destination for the world's best and brightest immigrants. "Immigrants have made tremendous personal sacrifices," said Wadhwa. "They would leave behind relatives and friends and accept second-tier status in American society.
"Now countries like India and China are providing equal career opportunities and a better quality of life. So the most highly educated and skilled are often returning home."
I recall with amusement the heated debates we used to have about the 'brain drain' and how to stop it. All sorts of prescriptions were given (eg compulsory home service before migrating, an exit fee for those departing from schools like the IITs, etc). None of this is required. When growth accelerates and creates opportunities, brain drain ceases to be an issue. Growth may not the complete answer to poverty but it is certainly an answer to brain drain.
