That is the crux of the education reform issue. Without getting into great detail on systems theory, you should understand that the education system is a system made of interconnecting, interrelating and interacting actors and processes. Together, the actors and processes stabilize at a self-defined equilibrium. If a system has a weak equilibrium, it's easy to change and the system dissipates or realigns itself in response to the change stimulus. The school system is very stable and has a strong equilibrium.
