A new study from the Institute for Development Policy and Management at the University of Manchester reveals some amazing findings about Chinese Gold Farmers.  You might take a look at the 87 page report: http://www.sed.manchester.ac.uk/idpm/research/publications/wp/di/di_wp32.htm

Among the findings, there is an estimated 125,000 - 325,000 gold farmers employed by some 60,000 enterprises in China, the workers making, on average, $145/month (that is a comparable wage in China).
