A charismatic leader can turn a nation into a super power. A leader needs to be brave, farsighted and diplomatic to build his nation. Without a leader a nation is like a unguided mob who don't know what to do. So for economic development leadership is important. Just look at how a country like japan became so well developed even they are low in natural resources. Malaysia and Vietnam can be a great example of that to show how leadership can change a countries economy.
