Its happened :/ - resorted to new character for Gil.

"people under 50 bragging about all the money they have"
"people at 50 complaining about all the money they lack"
solution: people at 50 sell things to people under 50. yeah some of that get's lost but we don't know if it's gone to the aether or if it determines quest gil gain, or if it's offset by the influx of new users with there bunches of gil.
if you are at 50 and you need a bunch of money, sell things to lower users. you get money, they get HQ stuff, win-win. leave the economics speculation to those who know how the system works.

It is not speculation it does not take a rocket scientist or an economist to tell you how the system works in this game. Its verysimple logic if you think about it. and none of that Market Board BS because players are putting that gil the market board does not actually create gil ....
