MA make their money from the difference between deposits and withdrawals.
Decay and loot return are set only so as to affect players' mentality.
If the balance between deposits and withdrawals ever don't cover MA's costs, then the RL creditors (employees, taxes, banks, etc), will get whatever cash MA have, any Ped balances or deposit history are irrelevant.
Building further on this, decay and quite some other fees and issues where MA takes money from the system are only meant to calculate some kind of safe bottom line of money in the system that MA should not consume. At the moment I believe their safe bottom line is very low, hence bad returns for a very long time already.
Visualized:
Total money in PE
------------------------------ A
Total in decay/fees
----------------------------- B
Money MA takes out of the system without decay/fees counterpart
------------------------------ C
Reserves
------------------------------ D
Bancrupcy
A-B= money that MA actually can use without doing any harm to the system. This money has been paid by the participants, directly to MA.
B-C= money that MAs balancing manager carefully has to balance in order to pay the bills on MAs side which exceed their income of A-B, meanwhile keeping the community happy enough to not see to many players leave out of frustration. Also the money paying for withdrawls. As soon as the withdrawl time is raising again this means that the balancing manager has taken to much from this part eg. MA needs to much from these reserves to pay the bills compared to the deposits they have received recently.
So, B-D= all money ingame which hasn't been paid to MA as decay or a fee. This money pays bills and withdrawls, forms the lootpool and represents the tt value of all ingame items.
B= the safe bottom line
C= the bankrupcy bottom line
As long as A-B pays for all MAs bills and thus B=C, the system is very healthy and the way I believe mr. Timkrans once envisioned his Universe. As soon as money from B-C is needed to pay for the bills things are getty tricky and I truly believe we are in this situation for A LOT of years already, no matter what MA says about what their income is. When bills need to be paid and the money is there, only on paper it would be wiser to not spend that money, you WILL use that money to pay the bills. Period!
As soon as C=D and all reserves are gone, MA would be bankrupt.
C is a very thin line to walk on, B as the bottomline for MAs income would be the fairest towards the plyers and the most healthiest for the EU economy. But I truly believe MA is struggling for years already to reach B=C.
Got that ya'll? Nothing else to it.
