You're wrong. This nation stated with a moral decline, We only were an economic power for a short time because Europe was devastated by 2 world wars in a 25-30 time frame. The decline of Africa began with colonization by whites . Continuing foreign policy by white nations are still fucking Africa up. Notice China, it has never been colonized by whites and it is a growing economy that we owe money to now.
You have no idea what you are talking about.
The Industrial revolution? Perhaps you have heard of it.
