World Balance is doomed until ..

[Theodric]

I am, slowly. Crafting is incredibly dull, so it takes me a while. But I won't perpetuate the cycle once I'm there, this stuff does not have any reason to cost that much for what it is.

You're paying for either a luxury and/or a convenience, though. Are some items very expensive? Definitely - especially if they're good for glamour purposes. Ultimately, though, you can get by with other items - dungeon drops, vendor purchases and so on - so there isn't necessarily a need to acquire specific pieces of gear from the market board. You could argue there's a necessity to buy high end crafted gear for progression purposes, of course, but high end raiders tend to make peace with the idea that to get ahead they need to shell out a hefty amount of gil.
