Teachers always grumble. Children need to be protected from the harsh realities of life. Good fences make good neighbours. Competition is the best way to motivate pupils. You must know where the money is coming from before you make the plan.
Principals get stale if they stay in the same job in the same school for too long.
You can't change the basic structure of how a school operates. Freedom is dangerous. Teachers and pupils will often take advantage of it. Rich and poor children mix like oil and water. The reason why LDSS has managed to integrate such wide-ranging activities is because of the emphasis it lays on compassion.
