It's just up to the members of a group to decide what is practical and desirable. So far this probably sounds pretty chaotic, with groups forming, fissioning and fusing every which way. But that's because we haven't yet gotten to what motivates everyone to actually do something useful. It all starts with the group at the very top of the hierarchy, which looks at how much is coming in and decides how much of it to throw into which pots. The way in which this money is distributed is key to maintaining the entrepreneurial spirit all the way down to the lowest levels of the hierarchy.
Every group is allocated a certain amount of money by the group above it.
This allocation is then divvied up among the affiliates of the group by consensus opinion. Ideally, the share that each affiliate gets should reflect how well it is doing whatever it's supposed to be doing. When you register your opinion on the distribution of funds you are actually evaluating the performance of the entire hierarchy that each member represents rather than the individuals themselves. Of course, some or all affiliates of your group might actually be individuals, in which case you are simply determining that person's salary. And of course, the size of the pie depends on the performance of your entire group as evaluated by members of the group above you, and so on up the tree.
