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.
It's sad but a very big problem in developing/ underdeveloped economies especially in African countries like Nigeria that how their literacy rates are damn too low and people still Live in the third world. Problem with these countries is the vicious circle actually, you have to do either of two things first, either educate your population too much so that companies come into your country to trade or bring in companies to generate employment so that people see lucrative opportunities and study. This is the reason development of human capital takes a lot of time.
