A person with a 'good child complex' externally all looks nice but on the inside, you are dealing with something petty with little ability to give and take.
The 'good child complex' finds it difficult to accept other people acting differently from those with the complex. They haven't had the freedom of the healthy child, being accepted and loved even when they don't act virtuously.
Parents who compliment their child for being good unconsciously desire to control the child. The child than suppresses behavior that will upset the parents at the same time preventing the child from developing normally their child-like nature. The results are often a neurosis.
The book shows ways of overcoming these problems. We have those who always want to be nice to others and can't express their opinion and become victims, feel injustice and built-up of anger—criticizing anger, creating a fake peace, as if there was no anger.
