If we look at the history some countries got maximum development in Dictator ship while some got maximum development in democratic government. Every system has it's own flaws and benefits. What do you like ? if we talk about the welfare of general people.
I prefer democracy, the people has a lot of freedom,of speech,to choose or to vote.and also has the right to cast out the one who runs the country who is not running well the government,be it local.
