People just don't get it. I'll try to explain but and I know only a few people will actually read this and even fewer of them will understand.

From leveling you make tons of money. Allegan coins from quests plus quest rewards and one off bonuses for things are very lucrative. However all of these things are one time pay offs.

Next consider this. Once you are in level 50 gear the cost for repairs is higher than you can make back with the gil creation mechanisms.

So we have less money coming in than going out. As time goes on there will be less and less money in the economy. Eventually there will be too little money for the economy to function. Even worse repair costs will still be there. This means an individual will only be able to play the game as much as their repairs allow.
