Actually the demonstration of their "class" status (are you English?) was to show that 30 years of premiedom has not prevented them having succesful lives in the wider society. Their HQ I judge myself on the basis of 30 years' acquaintance. I use the normal methods for determining this. You may notice that I haven't said they're all happy. I believe I left around 5 or 6 in the unhappier than normal category so I am able to make a distinction.Do you have any a priori beliefs that prevent you accepting taht many premies are happy?
