I think the actual Problem that you are running into is. is not that you think the economy is broken.
I think because of how the current system is and if you know how to play the system you willl have a quicker feeling of reaching endgame. Often confused with a broken economy because honestly . people blame that the gems are breaking the economy? HOWW You are not putting more money into the circulation by converting rubies into gems.

How ever you would put more money into the system if you were to sell your rubies to the miner npc.

Gems are just gona circulate and then be spend on the wheel in order to get money out of it.

I hope i made little sense in my post?
