Monaco has always conjured up the image of glamour, money,fame and success since Grace Kelly stepped foot on Monaco's soil. Grace first and then Caroline have both been great ambassors to their country. Now this legacy has passed on to Charlotte: She's the new ambassador of Monaco, because she's beautiful, glamourous, elegant, and she's the perfect successor to both Grace and Caroline. We - normal people - see her duties as hobbies, I mean attending parties, galas , magazine covers etc, but this is job for her. She's actually promoting the image of Monaco and helps build strong relationships with potential financial partners and so on.
This is her job, she is an extremely good " tool" to promote Monaco, and I don't see what's wrong with that.
She 's a heiress who could have lost her way and act all trashy and tacky like a Paris hilton but she's always been very prim and proper and behaved, no scandals or embarrassing things ever surfaced regarding Charlotte.
She may be not the most educated person on the face of the earth but I would not rule out the possibility that she's an avid reader.
So, this is just my two cents..
