Isnt that so simple?

Two simple steps:

1-> make "money source" = "money sinks"
2-> put unlimited L$ at 255/usd

Step 1 will force L$ to have more value, step 2 will force L$ to be at most 255/usd.
Philip Linden keeps saying: "SL needs more L$ for the increasing population",
so let SL decide this. If SL needs more L$, put unlimited L$ at 255/usd, demand will buy it.
I dont say "remove stipends" for step1 maybe reduce them, OR increase money sinks(or the current one's prices) to create a balance.

Thanks for your suggestion.
