It is in Nigeria that the life of the citizens doesn't concern the government

To be honest: The government is doing it right. In return, it should not concern you either, what the government is doing.

At the end of the day, politically, you can only vote once every couple of years. As a person, consumer and business alike, you vote multiple times every day: Food, roads, cloths, socializing. There's a hundred decisions every day, where you can pick the one thing or the other. It's entirely up to you what you make of that - and some make so much out of it that they don't need the government, but the government needs them.
