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 will choose democracy because first of all you have the free will to do what you want. It make sense the importance of human being in this world. Through democracy, our world will become peaceful and united as a nation/country.
