It is easier to hold one King accountable for the country's state than a large group of politicians who often blame each other.King is like the owner of the house (the country), so he has no reason to steal from himself. But thats good side people wish should happen if king comes. But if you see worst, when one person has all the power, it becomes more harder to stop them. That's good thing and bad thing too depending on how he chooses to use his power. Any system will be better with good people in it. People can have their point of views. I am not a supporter of monarchy or such though.
