I have yet to play a MMO where the developers haven't interfered with the markets in one fashion or another to make certain new players don't feel left out. If you're playing to accumulate wealth, you're just going to have to work harder.
You never played WoW? They never interfered until they started selling that gold thingy. Developers interfering with the in-game economy is sure to piss off more players than if they didn't.
