So many politician especially in Africa are only concern about their personal gain than improving the standard of living of their people. It's good to have personal interest in any political system but such interest should be in line to the interest of the masses otherwise it's wrong for a personal interest to be a disadvantage to the development and sustainability of the masses.
So you're blaming politicians who use politics for their interests? I don't blame leaders who voted or got elected and then failed to keep their word or do the right thing for their people. There is money in politics, and some people haven't seen or touched the type of money they see after coming to the position. That is why so many people have to steal as much as they can because they do not want to leave their previous life if they are no longer in that position, and some people steal money not by their means, but by the party that brought them out to compete for the position, and the person will do exactly as they instructed. Don't blame others for their political interests, everything has a reason, I believe if you're in that position, you will likely do the same. We should just pray for a good leader who will remember us when they get to the position they desire.
