the alternative is doing what our prisons do which is: lose money and have extremely high return rates of prisoners. Putting aside the fact that a lot of the prisoners are most likely (saying most likely because there's no way to get the truth of why the inmates are indeed inmates) serving for questionable crimes in the eyes of the world, china's certainly got this whole economic thing down. They essentially leech off of every facet of the USA economy from the high amount government bonds, to the middle class (toys in walmart, clothes) manufacturing goods and many foods, and now even video games. \
That point aside, why would anyone stop this. There will always be lazy people who will pay for gold in WoW. The server companies make money because the chinese prison guards have to pay for that accounts which makes the server companies more money based off of usage. And the inmates who in a more perfect world would be there for some crime they committed and rather than being supported by the tax payers like our inmates they're being forced to do something. And guess what, the government gets to tax the money that the prison guards make! So it's a win win for everybody except the prisoners who in my opinion have passed on their right to win.
