You could also make the comparison to how many banks there are in the world, which might be more like 4 or 5 thousand.Twelve banks make up the Federal Reserve Banking system. Each of those banks has just a tiny handful of shakers and movers, so let's say between 100 and 200 altogether.
4,300 and growing looks much better than a hundred or two.
And the number of people who will have influence on the system will go up dramatically with Evolution and proportional voting.
How many is enough in you opinion?
