Great idea, holding on to the worst kind of non democratic domination that the world have seen. Making a mockery out of all the millions of people who have fought and died ridding humanity of such trash ideas. Why the hell do people of Europe put up with this?
It's good for business: the royal family has an enormous network, and can open doors that will remain shut for "normal" politicians/leaders and such. They go on business trips with Dutch CEO's etc.
And: tourists love royalty! And palaces etc.
What would gossip magazines and websites and TV programs be without Royalty? It's a never ending source of entertainment!
