You are the third in line to the throne. He receives 6 million tax free per year to live off, plus his housing and travel is all paid for by the taxpayers of England. So he's only responsible for a few things and even most of those are things are donated to them like clothing and restaurant visits.
One of the things he has to cover is a housekeeper salary. Wouldn't it be a castle keeper? Anyways now till November 7th you can apply to live with Prince William and the Duchess as their housekeeper. Here's the link to the job description and chance to apply.
The position requires you to live at Kensington Palace, because you'll be on call 24 hours a day 7 day a week. You will also travel with the family so there will be no time off.
The pay for all of this is 25 grand per year. I literally just saw a posting for a fork lift driver in Lithonia GA paying 28 grand and that's 40 hours a week. C'mon royals!
