They don't understand it's the gold farmers keep price low, else the gold price would be way higher.
There's a guy I work with who use to make $30,000/year sell gold on a game called magic(I'm not 100% sure on the name of the game). Now the only reason he can't do the same with WOW is due to Chinese gold farmers.
The fact gold farmers are no different from any other Chinese labors. There's nothing to be ashamed about, at the end of the day it's a job.
