Not the kind of purpose I meant Cara. That is the Lady Bountiful routine which is de rigeur for any royal lady. When I said diferent lifestyle I meant something more consuming. Maybe a happy middle class lady called Caroline Nobody married to a nice doctor with three lovely kids and a happy, ordinary domestic life - saving up a holiday or something to aspire to and work towards, simple pleasures. Or indeed Caroline, politician of Nowherespecial, working hard on her local issues as a councillor or impassioned Caroline Ordinary with a high powered career as a surgeon. Something other than gilded advantage punctuated by a few charity meetings carrying a Dior briefcase or fundraising galas, eating nice food and appearing in a designer ballgown for charity. A real career or purpose of her own.
When you are born to royalty, you aren't just Carolien nobody. You are princess Caroline of Monaco. If you look at what Stefanie tried and failed to do as a designer or singer, that seems clear. They have both made a life for themselves, and your original post you wanted them to do something with the UN, or something more fufilling then a gilded life. Well they both do work with great organizations, which help people, more than we can say for some royals.
As for her children, internships and such do look impressive on resumes. One usually needs to get their feet wet, before a real job. And they are private citizens, unlike Willy and Waity, they aren't required to answer to the public. And while Charlotte doesn't seem to do much, other than her riding which is quite a commitment, her brothers have. They could sit on their ass and do nothing but they don't.
Andrea is not working because he is in school. He has a BA in visual arts and politics from the American University of Paris, spending a semester at McGill. He completed his first masters in international affairs at the New School in New York, and did work for the Quatari embassy, as part. He has since returned to school, for a second masters, in Barcelona, which he will complete in 2012. He taught in Africa for eight months, and makes regular trips abroad, when he isn't busy with school, for his mother's charity. An impressive education is nothing to sneer about.
Piere studied for his degree in internartional business in Italy. He has since been working with his father's business holdings, having taken over majority share holding of a construction company from his Uncle, with intentions to one day run the entire company. He now spends his time working in the Italian based company in Milan and Rome.
