In my opinion, the solution to underdevelopment in Nigeria is to structure the government in such a way that each state acts as a country of it's own with a central government handling mainly oversight. Each state will be required to develop itself using it's available human and natural resource and remitting only a fixed percentage of it's monthly IGR to central government in form of Tax.

Scrap off Senate, maintaining only Fed House of Rep to server as link to states and the central government.

These are my opinions, feel free to add to it or disagree with it.
