JOBS WHITE PEOPLE WON'T DO:

Over the coming decades, a labor shortage will force Levi and scores of other Western brands to remake their China operations or pack up and leave. The changes will mark a new chapter in the history of globalization, where automation is king, nearness to market is crucial and the lives of workers and consumers around the world are once again scrambled.

The stirrings of change are visible already. In an apparel factory in Zhongshan, a gritty city of three million stuffed with industrial parks across the Pearl River from Hong Kong, lasers are replacing dozens of workers who scrub Levi's blue jeans with sandpaper to give them the worn look that American consumers find stylish. Automated sewing machines have cut the number of seamstresses needed to stitch arc designs into back pockets. Digital printers make intricate patterns on jeans that workers used to do with a mesh screen.

"Labor is getting more expensive and technology is getting cheaper," says Andrew Lo, chief executive of Crystal Group, one of Levi's major suppliers in China.
