Look at that, SC fuzzy logic at work again. The last time it was at work we had War Levels. Might as well throw a wrench into the machine.
Warren Buffett gave his wealth to the Gates Foundation. He did not "give it to the poor". The difference is a world's a distance. He put the money to work in the foundation, and before that he put the money to work in the market. If Buffett had to reply, he would have said "put the money to use". Putting money to work here means: trading goods, trading GCs and loaning it. Donating money to the Security Council would be interesting; specially because the Security Council hasn't been receiving its taxes for months now.
W3C has a sickly knack to automatize everything. There's no fun in anything that is automatic; at the least, there's frustration. So let's try something different here and make some fun with the creation of a bond market. Let the forces of supply and demand define the interest rate and all that jazz.
This market would work fairly simple, because all bonds are backed by the World Bank, thus we don't have to take into consideration the country/empire/player who's asking for the money. To put supply and demand in work, an auction style market - as in the real world - would be setup, where everyone can see the bonds being issued and the interest rates bid. In order to buy a bond, your bid would have to be the smallest interest rate bid. Bonds would either be issued by the game when the country goes into the negative or by the player. These bonds offer should be up in the market for three days or something, they can be manually retracted, if proposed by the player or if there is positive cash on hand, but they cannot be manually accepted in order to prevent cheating.
Now... given there is no difference between exchange rates of the different worlds, this can be setup from the portal, and be used much liked the direct market. We bid X% from country X on world K on offer W.
As for the GM intervention, besides securing every loan/bond, he could automatically bid an X% interest rate, so as to mark a maximum interest rate. To make things interesting, X% could move depending on the average interest rate bid - or some other measure. So no abuse happens, X could move solely within a predetermined bound.
I can imagine a player coming to the forum or messaging his federation asking for other players to bid a lower interest rates on his bonds. Some players would cry for help, others would make a gag and a giggle. This kind of stuff is good for the game. Much better than having loans automatically issued and delivered.
In this style of market it is very difficult to cheat. Who's there to assure you someone else won't bid a lower interest rate? Plus, in the amazingly off chance he does manage to cheat, he'll be easily spotted, because his interest rates will be far above the market interest rate.
This feature is doable, safe and engaging. Basically, it would be a much needed extension of the Direct/Cash market.
I'll leave the "if costs are in game time and revenues are in real time isn't this a lark" discourse for another time.
