It's true that incompetent rulers can wreak a county economy and financial systems. Nigeria economic and system has be fragile. Corrupt and bad rulers who are making things worst for the people in the country. Making efforts of the people in Nigeria worthless and useless. The main issues is the age numbers problem of bad rulers. Where are the leaders of tomorrow, we can't take over because someone wicked old men refuse to handover. If this continues Nigeria is moving no where but backward.
