Northern Nigeria Produced the Richest Black Man on Earth Without Niger Delta Oil

 Why do some people think like uneducated idiots?
The north has produced the richest black man on earth, multi billionaire Alhaji ALIKO DANGOTE and he does not have a single oil block. He produces and sells cement, sugar, salt and other goods people need more than crude oil.

The north can survive and succeed without the Niger Delta.
The wealthiest countries in the world don't produce crude oil.
The north can dump the crude oil from Niger Delta and import from north Africa and the Middle East.
What is the use of being oil producing states, but have no brains to produce world class billionaires like Alhaji ALIKO DANGOTE?
