If this calculation is true then that is the main reason why Northern will never allow Biafra to have their freedom, because all the bigger revenue comes from south south and south east, apart from Lagos where south south and south east based as traders and business people, without them Lagos have no revenue to boost with. Lagos have bigger revenue because of the Containers IGBO's business men is shipping into through Apapa Wharf
Nice talk..... Without igbo., lagos is nothing.
