There is absolutely nothing wrong with Nigeria other than the fact that external interference has placed and entrenched the worst possible people in charge.
If it were a schoolbus, what happened is that someone outside opened the window, handed the Downs Syndrome kids AK47s, and got them to overthrow the driver.
Now the driver is dead, and a group of armed Downs Syndrome kids are fighting over the steering wheel while the bus is doing 75mph with all of us onboard.
The solution is whatever you think it is.
