Nigeria needs a revolution in its rulers’ approach to governance but it also needs a revolution in the people’s approach to citizenship. Assuming it is acceptable to be dishonest in business dealings simply because “everyone else is doing it” will get Nigeria nowhere; likewise will accepting the rule of the mediocre because “that’s just the way it is”.
I’m not too familiar with Nigeria, but I can certainly imagine that this may well be the case. It definitely is in one country I’ve had a bit of experience with recently: Nepal.
