What is the need for formal education if the product cannot rise above the level an illiterate is operating from?

I feel very sad when I see a Nigerian graduate thinking, reasoning, arguing and analyzing issues like an illiterate.

What’s the need for formal education if the product cannot rise above the level an illiterate is operating from?

Why waste at least 15 years of your first 20 years acquiring education you obviously do not need when you could have become an expert mechanic, carpenter, native doctor or bricklayer?

Some people pass through school but school no pass through them.

We can do better as Nigerians.
