In every nations this set of people is certainly there, many people work for years and gather experience, become exposed to politics and leadership, admire positions and opportunities to rule, if finally by virtue of elections you're vote into an office they assume a legal rights to steal and loot public funds,
They same person who was once working with all Obedience to serve their boss, will in a long run forget the past and pursuits selfish interest, I don't know if leadership automatically baptize one into corruption in some Africa nations and other part of the world using lobby as an approach to stealing public funds. But can nation like Nigeria that is so much with corruption fought corruption? Since the supposed leaders who was supposed to fight corruption are involved?
Almost all developing countries experience this situation because positions obtained through bribery ultimately lead to corruption and it may be difficult to prevent it if this electoral system remains in place. There is a term "reciprocity" that refers to the position given, which leads to someone serving the interests of the leader and this generally occurs in several cases, especially in my country. Many leaders steal public funds, often referred to as corruption and do so because they have the opportunity or even the means to do so.
To combat corruption, decisive action is necessary, including severe penalties to create a deterrent effect. Furthermore, they should be stripped of their political rights to hold public office. This way, those caught in corruption cases will no longer have the opportunity to enter power, as the ethics of most politicians are now much worse and difficult to trust.
