The Chinese are very innovative, even in slave labor:
As a prisoner at the Jixi labour camp, Liu Dali would slog through tough days breaking rocks and digging trenches in the open cast coalmines of north-east China. By night, he would slay demons, battle goblins and cast spells. Liu says he was one of scores of prisoners forced to play online games to build up credits that prison guards would then trade for real money. The 54-year-old, a former prison guard who was jailed for three years in 2004 for "illegally petitioning" the central government about corruption in his hometown, reckons the operation was even more lucrative than the physical labour that prisoners were also forced to do.
In video game jargon this is called "farming." I think we need tariffs against virtual gold. We need to allow our young people to be competitive in video games! If we Americans can not be competitive in playing video games, how can we be competitive anywhere?
