Unfortunately many of Chairman Mao's other ideas have proven to be quite costly and quite painful especially to the family. We have all learned in a very personal way that ideas have consequences. For example, one of Chairman Mao's most devastating tenets that still grips our nation today was the concept that the family is subservient to the state. The family exists to further the best interests of the state. The state, in essence, is God.
All rights flow from it.
All things exist for its benefit. Children unfortunately are no exception. Parents are allowed to keep children as long as their beliefs do not contradict those of the state. The state dictates the number. The state dictates what they will be taught and where.
