Is the Naira devaluation the cause of all the problems for not growing? No.
Nigeria should move from consumption country to a productive country this will help to foster the development. The Government always try's to implement what could give them more avenue to loot from the poor masses, which is the greatest problem every country would like face if not elect sound and educated leaders into power.
Lastly I think the ruling party and leaders those in power are old enough to be retired to give a young vibrant youths to seat to know the best structure the country needs and wants.
Did all the businessmen and women know how to use the enaira? Most of them can not use ecurrency because they are computer illiteracy. CBN devalues the nairra to boost the country's economy but ironically the Americans were more wiser than the Nigerian Government. The world order says, Nigeria should consume while the developed countries should produce.
