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.
If we will be talking about the welfare of the people, I will go with democracy. This is a type of government wherein it is run by the people and for the people. But for this type is often abused and taken for granted by also the people. But still, democracy is the best type of government.
