I think Laura is actually living in Shanghai. The children of Astrid and Lorenz seem to be intelligent, well-educated and most importantly seem to have their hearts and heads in the right place.
They've figured out that they'd better not count on tax money and a lot of royal duties, at least. When you think about it, they're in the same position as the York girls, but they're not clinging to the royal life with teeth and claws. Amedeo especially; they had him in line to succeed Philippe eventually until Elisabeth was born, and he got the full heir-to-the-heir education and attention for a large part of his life. It's good to see that he isn't insisting on it and that he does his own thing instead.
