IMO MMORPGs and Money are a bad Combo. Money isn't evil or wrong, but the Extreme our World's Society has taken Money too is quite evil (selfish) in my opinion. Selfishness = Evil. There are some things that should never be "For Profit" such as Health Care, Religions, and Governments and their Armies, and in this context MMORPGs.
In a world where Money is everything like our World is now, We as People cease to be People and are just Property Assets. Someday People will get tired of being classified as Property.
