What is better to have, a corrupt democracy or a benevolent dictator?
A perfectly benevolent dictator is one of the best forms of government imaginable, second only to pure socialism in my opinion. Different forms of government exist to provide the greatest possible good for their respective citizens, but if we hypothetically say that whomever is in power is looking foremost for the good of the citizens, then the form of government serves a different role. If those in power are assumed to be perfectly benevolent, a dictatorship is the best form of government because it is the most efficient, and is therefore able to deliver a greater good to the citizens with less waste.
