There is a reason why democracy is chosen as the best system of government because everyone has that free speech and you have that right to complain about anything that is bad in the economy
No, that's not the reason why Democracy is the best form of governance. Overall, I would say that dictatorship is the best form of governance only in the case when dictator is well-educated and patriot of his nation but the chance of finding such dictator is slim to none, especially now. Today, democracy is the best because it sounds more fair but the huge negative side of democracy is that the majority of people, i.e. average John Doe decide your fate. If we keep in mind that average Joe is not smart, then it translates the following way: Not so smart citizens decide the fate of everyone.
But if we sum up every forms of governance, democracy is still most fair and the best compared to other forms.
