No society will grow or develop when the leaders or government aren't doing their job right. Many failed society was colb as the result bad form of government projected powers and administrative costs. Many Africa leaders are fixed or low in development priorities or even society. When leaders fails in their capacity to build expected society it cause such societal crime and poverty-stricken members.
This also can lead to poor standard of living, bad government ruins the beauty of progressive society and create unemployment, bad government detorate peace and escalate hunger, theft, insecurities and cyber crime to the youth as only give choices where a failed leader is the head.
The African society needs to build stronger institutions, the reason why there have been persistent leaders who are not interested in developing the African society is because the institutions are weak, from the judiciary, the legislation, security and executive are all weak and that's why past leaders can easily go away with their wrong deeds while passing the same message to their successor's, if people are held accountable for their stewardship while in office, certainly they will be cautious while delivering their services. The society you see today that are develop did not get leaders from the sky, it was conscious effort by citizens to make sure that those institutions makes everybody to account for every penny spent, and at the end of the day you see a society develop to enviable height, else you will end up building strong individuals instead of strong institutions.
