As a producer I can tell you that I find it refreshing to have a game where I can actually compete. Instead of tiredly posting something on an auction or market and watch people inflate an item that prices out the poorer player or new player.
Unless you have actual statistic that shows producers are quitting the game. I have to wonder where you are getting this information.
Also CCP just before the convention quietly announced that they had hired on a new economist to look over what is happening in the market.
What we are seeing with the end of the scarcity and other small changes market wise is from that hire.
