The Pearl children are so happy??

Hi,
I have read a lot of the Pearl literature -- just from the newsletters on their website, not actually their books. I have also had experience with Ezzo - my first child was a perfect Ezzo baby (and now at 5 and a half is nearly healed of that horrible stuff we put him through. Praise God!) But one thing that I can't understand is why the Pearl children (three of whom are young married women who seem to write such inspirational stuff in the newsletters) are so seemingly godly, well-rounded and happy people. When I look for advice on parenting, I like to look to people who have the fruit. The Pearls, even though I don't know them personally, seem to have the fruit - adult children walking with God. What does everyone else think of that? I am in total agreement that their punitive measures of discipline are way over the top, but mustn't they be doing something right to get such great kids? Anyway, I'm interested to hear anyone else's views on this.

Thanks.
