It is due to the fact that linear models almost always assume that we evolve as industries or organizations, but not as individuals. They do not assume that one individual, with the flick of a switch or a hateful statement, can stop the presses. The hierarchy of prosperity represents order, just like the command and control form of management, because it assumes that evolution is a lock-step process. I think teams are a good idea. The concept of teams provides a way of breaking an organization down into functional or value-creating areas in order to maximize the chance of breakthrough improvements in those areas.
Teams make better decisions, and are often more creative, collectively, than individuals.
However, the evolution of a team is the collective evolution of the members of the team. That means that there are as many I's in TEAM as their are members of the team. In a team of five people, we have the chance of finding up to five individual superstars who could each break ahead of the pack in terms of learning and development. They could each become leaders who figure out how to drive productivity off the charts, and raise the standard of living of every individual in the organization while discovering the next golden goose of prosperity. I know this isn't the way the world typically works.
