I think that line of thought is on the right track. The reason money hold value is that they are a scarce resource. Some can have more than others, but only if they have earned it. Thus users with more "money in the bank" can have a stronger say. (note similarity with real world ;-))

The major problem with modding systems as they are today (in my humble opinion, that is) is that there are no scarcity. We all have all the money in the world, so to speak.

What this means is that we don't save our mod points, submissions or whatever because there is no cost in losing them. We can give away money and still have an unlimited amount. And we all have equal amounts.

We need to go from socialist to a capitalist modding systems :-)

But where should it all come from? Perhaps PG would play the FED's part?
