Said it before I'll say it again.

For everyone complaining that they can't get enough gil:

They think that gil should be earned through quests/leves/dungeons. That somehow by simply doing these things they should obtain wealth. But that wealth is only a means to an end... it is the stuff that you can buy with that gil that is desireable.

In reality, wealth is just a representation of the service you have done for someone else. If you make 3000 meat mithkabobs for people and sell them, they will give you gil. The only reason they have gil to give, is because they did something for someone else. In reality all we are doing is doing is serving the needs and wants of each other. The gil is just a representation of how much you have done for others and is a way to command the services of others in proportion to what you have done for everyone else.

This is how an economy is supposed to function. You have to do things that create value for others. If you have no use, then you won't make gil. Don't expect to be able to farm leves all day, something that provides no benefit for the rest of us, and expect to be able to buy things.
