This is a nice question. Yeah, it is a result of liberal humanism. This system gives the children much freedom and snatched paternal power significantly. You can't rise your hand against your child, you can't scold your child the way you like. All of this may end up in your kid being taken away by officials. There is no better system than this at this time but definitely not what we want. Whatever the reason, I support this system than the way most Ethiopians rise their child.
