Most parents want the best for their children, but in most cases they have no clue what they are doing. Because it has never been learned or experienced. And "we'll see what happens" is not very solid for such an important task.
I also believe if you raise children the wrong way, you will damage them and probably forever. Insecurity is not easy to get rid of. Insecurity is something that starts during childhood. Because of the wrong approach by parents.
