That is precisely why you have the values and morals that you have today. You were raised that way, regardless of how you may feel that the way that they raise thier kids is wrong, it is a way of raising one's children with a lot of positive attitudes towards teamwork and getting the job done together. They are passing on thier values and morals to thier children. As well, the children do have a chance to explore the outside world and see if that is the way they wish to live thier lives, (or perhaps it is the Amish), at the mid point of the teen years.
One parent may find it repugnant that you took your 5 year old daughter out for a weekend fishing trip in the middle of no-where, (I find it laudable), as one should not expose ones' childern to the dangers of the wilderness. Once again an example of different values in play.
Just my two cents.
