Viet_Nam proposed that we use a closed economy, to stop the flow of meebles and such. While the idea is very intruiging, this system should not be applied to everything, and in fact, very few things.
First off, money made from town taxes will go into the closed economy, same as always. However, I did see a suggestion to bring unique items into /warp shop, so you could incorporate that at a later date.
Voting is probably the main cause of money being brought into the economy, so apply that to the closed economy. That should stop about 300K-ish being created every day.
Jobs, parkour, and minigames should be left alone, because the amount of money being brought in depends on how much the players work for it. And if there's a lot of money coming in, well, that's good, because the players are actually working for it (unless working for it isn't fun)
The closed economy idea needs some sort of reward. Sure, there's no money entering the economy, but that's okay, because you get your 30K and log off, same as always. Something needs to be added to jobs and the other things, to make the idea of working for meebles interesting for those people who just vote and log off. I don't know what that could be, and a nerf or a buff may not cut it.
