According to who?
According to history
How is it false? Do you have any relatives in Nigeria? Ask them how much of their money is in the banks. And the banking system as we know it didn't exist in the late 1700s so that's not a fair comparison.
Its false because you can't expect a 60 year old country to have the infrastructure of a 250 year old country.
And what do you mean "banking system as we know it didn't exist" .... the institutions and bankers of 1700 are the same as today
10 years is a long time in regards to technology, but not in regards to economics.
Technology subverts economics. Look at the remittances economy just in the time mobile money caught on.
You notice that I did specifically say Nigerian business owners right?
Who have obvious biases and have no care for social infrastructure and public goods
