The markets are too small for normal market forces to operate as they should, since they are segregated among servers. As production increases the value of money rises as the price of goods falls. Production is good for everyone, even the crafter, since his costs will go down as well and the value of his sales will rise, although the actual numerical value of the price might fall.

A Bid/Ask system in the market would be a step in the right direction. But the true goal should be a common market among all servers of the same kind. This would control prices at a more reasonable level since we could gauge the demand of particulars more accurately.

The crafters enjoyed a period of very easy money, where people coming hot of their quests had cash burning holes in their pockets. These people have gil in the 10s and 100s of millions. I know a few players who managed this in the first few weeks of the game. Those times are over, and the game is better for it.
