What can be learnt from the New Jersey Housewives?

We have learnt so far this season from the NJ Housewives that family is important. We learn that if someone shares a different view point from our family we should automatically black list them and go as far as to attack them. There is no room for acceptance of differences in no shape or form. If you had problems in your past, you cannot be a better person and you will always where, like in the Scarlet Letter, an A on your chest. We learnt to fight it out and not to talk it out. We learnt that friends are very temporary and the very minute you slip-up, your friends are gone. Friends do not keep secrets and your closest friend is you biggest enemy. A lot of other lessons to be learnt in this show. Can you tell me some other lessons you learnt? And what can we talk away from this show as positive?
