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 think democracy is much better than dictatorship. With democracy, people can choose their political leaders through voting. The people can also oust abusive ones by uniting for the said goal. Dictatorship can also be great but only with a good leader who puts the people before himself. The amount of power given to one individual is way too risky though. The probability of a dictator turning into an abusive leader or a tyrant is always high.
