According to the papers William has at least 90 household staff. Footmen and doormen, chauffeurs, cleaners, laudrymen, butlers, personal assistants, garners, cooks, maids, secretaries etc. He's paid millions to show up for social events. Even celebrities work hard to earn their status before being invited to such events.
The tax payers pay for him, Kate etc and should be informed about how they're spending their time especially when they don't show up in spite of all the clothing allowance, cars, chauffeurs, stylists etc paid for by poor commoners.
Katie's sister and mum are busy holidaying and having a grand time. Showing up at a service is not work.
William is L-A-Z-Y and E-N-T-T-I-T-L-E-D. He's happy to take the money, pay no taxes but the public must not ask questions while he directs his press off to leak stories about the better brother. Horrid!
