The royals getting married have accomplished nothing deserving of attention. It takes no work or effort to be born a prince. The fact that so many people get emotionally invested in people they've never met, purely because of their accident of birth and not because they've actually accomplished anything, strikes me as just odd.
Oh, please. Very few people are invested emotionally in the Royals (although I was a huge fan of Diana). They tune into the weddings and coronations and funerals because of the English genuis for pageantry. The beauty of their traditions knock the socks off people - particularly anyone with an eye for beauty, design and bloody brilliant organization. Have you never visited a museum to look at Royal Egyptian art? Romanov art? Hapsburg art, design and the awe-inspiring Royal carriages?
