I think the biggest point to this whole argument is that this is an optional thing. You are complaining about something you do not remotely need to spend Gil on. SE has done a really good job of making sure that crafting is not needed for 95% of the games content. The only 3 areas it really comes to play in are the Relic quest, Housing and Vanity. Why do you begrudge the crafters for making money on something that you can simply live without? Economy is driven off demand, if you don't want it, don't buy in. Eventually the cost of prisms will drop to near production cost just like everything else on the market and you will be able to glamour just about any outfit for the Gil you make in 1 extreme roulette.
