The adage (school na scam)by most Nigerian is becoming realistic.for a country to grow and develop,it most invest in is human capital.presently.universities, polytechnics and colleges are on strike.the educational system of the country is very poor.
Another problem is high unemployment rate: most graduate that are are qualified and ready to work,are not employed which is decrease the rate at which people go to school.
With the poor educational system of the country, skills acquisition and empowerment is also low which worsened the situation.
I don't understand, you contradict the title of this thread by the first couple sentences of your message? Education is definitely the most powerful tool that a country has to becoming richer and more successful. The higher education you are and the people around you, the more innovative ideas are bound to sprout. If the education system is poorly designed and unable to cope with the needs of the population that is a whole other story, although I suspect there are some very good schools in Nigeria, but the majority might be underfunded or have incompetent teaching staff. Teaching is a very tough job at the best of times, but in poorer countries it is even harder as the really knowledgeable teachers are bound to flock into other professions than face the stress.
