Its no news Nigeria’s decline began in the mid eighties when the military took over. What is interesting however is when you realize that about 22yrs ago (1990) Nigeria and China had the same GDP Per Capita. At that point, China had basically caught up with Nigeria and of course never looked back. As the graph below also shows, the decline started at about 1984 when the Buhari, Babangida and their cohorts took over.
This is perhaps one more proof of the damage Babangida and the military brought upon Nigeria.
