My guess is that it would probably be very similar to real world economics, where 1% of the people own 99% of the wealth.
If they start posting confirmations on this, we’ll end up with an “occupy wall street” movement in game. Players flooding the trading post in protest. Players refusing to buy/sell materials until changes are made to the game. Huge market crashes as the wealthy players try to offload everything they own in response. Chaos.
While there will be some superficial similarities, I seriously doubt the wealth inequality in game will mirror real world inequality as there are a number of factors that drive inequality in real economies that don’t exist in-game
For example, in the real world, having wealth enables you to create/find rent-seeking (http://en.wikipedia.org/wiki/Rent_seeking) opportunities that don’t exist in this virtual economy. As a result, those who have already wealth in this game are generally not able to use that wealth to prevent others from gaining wealth.
You are correct. There are several good reasons why wealth distributions in game don’t mimic the US Economy.
Another reason is that the growth of wealth is exponential in many developed economies, where it’s closer to logarithmic in GW2.
The entire set of reasons would be a very interesting discussion…Well for me at least
