As a server, please don't interfere too much. As far as I'm concerned, the economic duties of a server are:
- Nerfing broken ways to get money or a specific item a certain way (as with iron and diamonds now. Mcmmo and 1.14 villagers come together in a way to multiply profits, and as much as it pains me to say it, that should be nerfed).
- Defining buy/sell prices (but I see no good in changing them now - more expensive buy prices? Only new players buy there for the most part. Cheaper sell? Will only allow for iron/diamond prices to drop even further)
- (And, if you really dislike players having money:) Supply ways for players to spend money. But please, keep this reasonable and voluntary.
NOT duties of a server:
- Price-policing "this item 'ought' to sell for 100 even though the shop sell price is 20"
Again please don't interfere too much. The economy is a fun balance of supply/demand where people have different goals but everyone can participate. Prices will shift based on supply/demand, which is natural and expected. Having a stable economy does NOT mean having prices that never change. The balance of supply/demand IS the economy, and as long as there are no 'broken' loopholes of getting items, IMO the server should't interfere.
In a minecraft server there will always be an inbalance of wealth. Because for some people (including me), getting to /baltop 1 is a cool achievement which I work hard for, while others don't care at all as long as they have some pocket money to buy things they want. Please, as a server, do not enforce one of these play styles as "more correct" over others. Everyone has fun in minecraft in their own way. (Again, only way I see interference as beneficial is nerfing broken
ways to get money, NOT by cracking down the
people who have "too much money")
The funny thing is, I'm noticing two different themes here: "there's too much money in the economy" but this seems to be spawned by "as an old player I can't sell diamond for the price I used to and I feel robbed now". Note that these two are contradictory. Old, rich players want to make money as easily as before (even though there is now more competition and more supply of items), hence only becoming richer. But to that I say, don't expect prices to remain constant. They are governed by supply and demand, which is the whole fun of it. If you want to influence someone's prices, talk to them. If they're really unreasonable about it, heck, hunt them
No need to ask for the server "government" to protect your profit margins.
Auction house: Sure, Auction house makes physical shops less visited. But auction house is the best way for new players to sell their things. With only physical shops, how would new players sell their things? In chat?? (pls no). Also, why would everyone need to build their own physical shop? Some people like them, some don't.
Inflating economy: Yes, the economy is inflating, but in real life this happens too and is natural and healthy. I do like the suggestion of adding new ways to spend money (again, please keep voluntary). Loot crates containing unobtainable enchants (Unbreaking 4 and things) are something I'd buy.
Shop prices mentioned above, I don't see changing them having a positive effect.
