I would prefer to be leader by a group of elected officials who "truly wanted the best for the people."
There have been a handful of monarchs through history who have ruled in a beneficial way, but without a concrete method of checks against absolute power, it is a temptation that nobody can resist. At the same time, the enormous complexity of our nation could not be realistically handled by one man. That is one problem with the office of the President - no one man can understand and manage our country. Theoretically, our 535 other elected representatives should be able to handle the breadth of our country better, but we certainly haven't seen that. Instead, our leaders are most decidedly NOT people who "truly want the best for the people." They are motivated by huge campaign contributions and the desire to stay in power by getting re-elected. I can't think of the time I last heard of any politician who represented any of my values at all. And since most of them live in the Beltway fantasyland, they have no idea what this country needs.
I don't know about a monarch, but I would love to see our leadership become knowledgeable, selfless, humble, visionary, and devoted to what is best for our country.
I am most assuredly NOT holding my breath...
