Does leadership improve societies?

So much will depend on whether the leadership is good or bad. When corrupt and self-serving, then whatever leadership there is will focus purely on individual goals such as power and money with little or no regard for the people these leaders are supposed to represent and serve. How often have we seen this engender a level of discontent that leads to rioting or even civil war, driven by the desire for ultimate power?

Not everyone wants to be a leader and good leadership is undoubtedly of huge benefit to society. Having a figure-head who is respected and admired will encourage people to follow their lead and support them in their endeavours. This provides cohesion and a general sense of contentment which leads to greater productivity and a greater feeling of overall well-being.
