Washington Post
(I hope the link still works..WashPost is planning to require registrations soon..)

here are a couple relevant paragraphs to give the flavor:
"SHENZHEN, China -- Inside the factory, amid clattering machinery and clouds of sawdust, men without earplugs or protective goggles feed wood into screaming electric saws, making cabinets for stereo speakers. Women hunch over worktables, many hands bandaged and few covered by gloves, pressing transistors into circuit boards... A sign on the wall reminds them of their expendability in a nation with hundreds of millions of surplus workers: "If you don't work hard today, tomorrow you'll have to try hard to look for a job."

""The profit is really small," said Surely Huang, a factory engineer, speaking of the 350,000 stereos that Fenda agreed in March to supply to the retailer for $30 to $40 each. Huang said they sell for $50 in the United States. "We have to constantly cut costs to satisfy Wal-Mart."
"Wal-Mart pressures the factory to cut its price, and the factory responds with longer hours or lower pay," said a Chinese labor official, who declined to be named for fear of punishment. "And the workers have no options."

lots more...............There's your low prices, Martin and Clinton...
