You think the solution to poverty is guns?
Gun manufacturing is a profitable business, especially if all the common people of Africa who don't have guns buy them.
The people could be employed at the gun and munitions plants and earn good money. They could take guns home with them to protect their families from foreign invaders.
As skills among Africans increased, they might even get into the manufacture of nukes.
Right now, the country of South Africa is the only notable place in Africa where guns and armament are manufactured. If it spread throughout Africa, Africa could stand up and take its place in the modern world, just like South Africa has.
Of course, all the things associated with guns would have to be included in the package - gun safety training and gun laws and rights.
The problem with this whole idea might be the low mental IQ of much of Africa combined with their high emotional IQ. Africa just might be the place that a populace that had open carry might be constantly getting into gun battles with their neighbors over nothing... just for the fun of it.
