Nigeria owes it's gdp growth to the size of its consumer market.So if we populate well we may as well come tops because there's nothing much save for corruption, epileptic power supply, unemployment, bad roads, embezzlement of public funds, ethnic and religious killings, strikes, terrorist attacks, ritual killings and other social vices in that place.
Nigeria imo is just big in papers but the reality on the ground is diff.
We have even struck oil,the only one commodity which seems to push Nigeria ahead because of the high price of crude oil.
Compare our exports with Nigeria's. We even have a dreamliner while they have Arik!ok i am jealous.
We have better infrastructure,better power supply,better healthcare,better buildings,better goverment (i know i know).
Investors rush to nigeria because of the large consumer market but other factors dissuade them from fully investing -some are pulling out for security reasons,infrastructure and corruption.
How can a big economy like nigeria fair worse than those with a small one like us.It's therefore not proper to gauge a country's develpt by its GDP size alone.
