Why the downvotes? A democratic country should not have kings and queens, regardless of whether they have real power or not. Why should a person be so special in a democracy just because they have the right ancestors?

They function as safeguards against a truly insane government. If they live up to that expectation I don't know but I suppose it's better than nothing.

I pay about one Euro per month for ours. I can afford it. The king also has very high approval rating. People don't want him removed.

In the Commonwealth at least, the monarch or their representative is basically just acting as the failsafe that decides if the government is fucked and needs to be turned off and on again.
