Hello, I'm Mayra Anubi.
Welcome to People Fixing the World from the BBC World Service,
where we explore solutions to the planet's problems.
People Fixing the World returns soon, but until then, we are bringing you a special episode.
In No Brother Left Behind,
Chiagozie Anwarwar explores the tradition of the Igbaboy apprenticeship scheme and why it is now at risk of fading out in modern Nigeria.
This is no brother left behind from the BBC World Service with me, Thiago Zenwongo.
Somebody met me the other day and said, do you have any allergy?
I said, yes.
They said, OK, what is it?
So we'll be careful.
I told him poverty.
That's my number one allergy.
I have tested it.
I don't want to know what it looks like again.
This is Cosmos Madoka.
He's an evil businessman and the founder and chairman of the Costa Riz Group,
a multi-million dollar Nigerian company whose main business is in motor spare parts and luxury car sales.
We are sitting in a cavernous room in Kosman's home, one that can easily hold 50 to 70 people,
and the house is in one of the richest neighborhoods in Nigeria.
