But consider what happens if I make my kid 90% of what I think is good. Then he takes his values, and makes his kid 90% of that. And then the next kid is 90% as good as his parents. And so on. See how it gets worse every generation? As a percentage of the original, the generations go 90%, 81%, 73%, 66%, 59%, etc
TCS aims for children to be even better than their parents. For that to happen, they are going to need to be something more than not quite perfect copies of their parents. You can't just take the parent, copy it with only a couple flaws, and call it better. That's obviously going to be a little worse.
Children, to turn out better than their parents, are going to have to disagree with their parents about at least one thing, and be right. Parents need to allow and encourage that, not suppress it.
