My first choice would be MONACO. An unlimited clothing budget, palatial seaside castles and villas, a share in the best gene pool in the Gotha as far as looks are concerned, glamour up the wazoo, no disrespectful press and no surly taxpayers nipping at my heels at my lack of work ethic...I could go on endless holidays and fashion shows. The downside is that I'd probably have a miserable love life because that seems to the the Grimaldi lot.
Which leads me to my 2nd choice...LUXEMBOURG!!
Again, I'd have an unlimited clothing budget even though I'd have to be more conservative than if I lived in Monte Carlo. I'd have a seemingly close, warm, loving family. The international paps wouldn't harass me that much, so I could also have a modicum of privacy in addition to a truly luxurious lifestyle. And all the marriages in that family seem straight out of a fairy tale. Money, prestige, lucky in love...what more could a person want?
You couldn't pay me to belong to the RF's of Britain, Spain or Belgium. What a nightmare.
