I don't know, it seems like the options for fixing this are limited.
As more of anything spawns, the market supply increases. Everyone would cry if they couldn't farm monsters for good stuff like gems. So at higher levels, great gems are spawning, and then they are going on the market, increasing supply and driving the price toward zero.
You could make gems decay in storage to take them out of circulation, but everyone will cry. You could make gems into very fragile/limited-use items, but everyone will cry. You could increase the work required to generate gems, now they will not be accessible to anyone except by buying from Chinese gold farmers or working Diablo like a job.
All you can do is forbid any kind of selling of gems (or whatever). But then the entire market is the black market and again the game is run by people who are using automation to produce items to sell for cash. So you actually have to prevent transfer of ownership altogether... but nobody suggests that because it doesn't sound like any fun.
And anyway, even if you do that you will still have people paying for someone else to level up their character and get goodies.
