Bertie, I agree with you for the most part except on two points, I doubt that, at the age of 8 she would know what kind of settlements were handed out, unless someone (Most likely her mother) told her. Four or five years down the line? Yes, she would and, considering the way her mother is portrayed, along with the things her cousins get away with, yes it could've affected her and her sister.
As for not helping Andrew with his bad press. What are they supposed to do? He's the one who takes a helicopter instead of a car to deliver a trophy, he's plays golf so often that his handicap is good enough to qualify him as a teacher according to one pro, he's the one who continually accepts Fergie's antics. He's brought in on himself.
Anything short of cutting him off, how is his family supposed to stop him from making an ass of himself. He comes off as a spoiled rich kid. Maybe they screwed up rising him but he's in his 50's, like Sarah he's got to grow up.
