Wanted: A New Business Model

There seem to be three general components to our economic system: producers, consumers and the system.  Within the producers classification there are many types.  One type that deserves calling out is the innovator.  So now we separate the system into four parts: producers, innovators, consumers and the system.  By the system, I mean the mechanisms that coordinate behavior in the economy and keep things running smoothly.  Examples include accountants, lawyers, and, perhaps most conspicuously, bankers.  My questions are these:

• Of the value that our economic system generates, how much is each group capturing?
• To maximize the benefit to society, how much should each group capture?
• If our current system is not allocating value optimally, is there a better system?
