Stranger:He may still make mistakes, anyone human will, but he will not gain from them. Democracy rewards the mistakes. Monarchy punishes them. Hence, monarchy is preferable to democracy.

The critical difference is time preference. Bush's opportunity to profit from graft, corruption, etc., is guaranteed to end in January--so he needs to get while the getting's good. Ideally, he should suck the country 100% dry on exactly the day he leaves office, taking with him the entire nation's wealth. He can't, by a long shot, but he's doing the best he can--just as Clinton did before him, etc.
As a monarch, he would have an incentive to preserve his personal capital by keeping the nation productive in 2009, 2010 and onward, for him to continue preying upon. The strategy that makes sense under term limits is, to a monarch, killing the golden goose.
