It's a shame that most people don't research on how to repair their equipment as cheap as possible at level 50. The economy is a gil sink currently. However once everyone knows how to repair their equipment efficiently, the gil sink would be a lot smaller. People can walk to their destination to save a couple of gil with the worst route being between Limsa and Ul'dah if you want to avoid paying the ferries. That only leaves market tax and people who doesn't have the patience to walk.
