Other than the fact that it is the fashion in THIS PARTICULAR ERA to diffuse jealous jibes about not "contributing to society" by doing something in the marketplace, WHY should it be better for these people to get "jobs"
If one finds something for which one feels a passion, sure, go ahead and work, by all means; if, however, you don't really need the money for survival and you aren't drawn to any one particular thing to the degree that you wish to pursue it as an occupation why should you?
Again, careerism has only become such an absolute requirement for social approval in the past...what...twenty-five years?
Not everyone has middle class needs or values nor should they be forced, at the risk of some society mob mentality and the pop opinion of the period to all follow the same paths.
Having something with which to occupy your mind and focus your desires is a fine thing, but that needn't be a "job" it could just be an enjoyable hobby.
And no, I don't subscribe to the insulting doctrine that everyone is going to tend toward vicious or negative habits unless their minds are taken up with performing some task for an outside entity; in fact people who DO subscribe to such a jaundiced view tell us a heck of a lot more about themselves and how they have been raised to view themselves and others than anything else.
I'm sure many of us have the inner resources to actually enjoy and use free time without resorting to crime or self destructive habits.
This is not to say that pursuing an outside career is bad, only that it is no more a one size fits all answer today as the idea that all women needed to marry and have children was the best idea 50 years ago.
As for Queen Elizabeth, this get a job stuff is every bit as much a 21st century sop to public opinion as was the virginity madness that Lady Diana was put through back in the '80s.
Let these women be themselves, and make your decisions from there. The lesson should have been learned.
For all that, Charlotte looks beautiful as always and I'm sure that given her background the things that attract her in a boyfriend are quite different from those that appeal to me (admittedly I'm 45). Still I'm really surprised that the realationship with Alex has lasted this long. I wonder if he would have made as much effort with another non-royal connected society girl.
