A little off topic, but over the weekend I watched a program on the Australia Network called Foreign Correspondent. They had a story on a migrant worker in a jeans factory (I assume in Guangdong somewhere). The working and living conditions were very poor and they were making jeans for a European business. It was a repeat, as I had seen it previously, but can't find a link to the actual show.
Here is another story from the same program, also about the challenges that migrant workers have in China. It first aired in March, but has some interesting insights into how the current financial crisis is effecting manufacturing in China.
