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 is unfortunate there is a strike but you can always do what you can to learn on your own since education will always be the key to a better future, even if those people cannot find a job in their country if they are any good they can always offer their skills online or if they are excellent they could always emigrate to another country with more opportunities and improve their lives that way, it is unfortunate those people cannot earn a living on the profession they went to college to learn, but this is a problem that happens at many poor countries and that is not exclusive to Nigeria, however even if those people work abroad they will send money to their families on their native country and slowly begin a process of change which will modernize the country, unfortunately this is not something that happens overnight and it will take decades if things go right.
