Slaves helped build the USA, and when the slave trade stoped, Africa lost a revenue source their economy's depended on.
please watch this video as my summary does not do it justice, I would also recommend TEDed video on The rise of Hitler. Please watch the Video and judge for yourself.
Africa's problems stem largely from its turbulent past. The colonial powers in Europe took over control of different parts of Africa. They created borders where none existed and created countries consisting of tribes who didn't like each other. They turned the people against each other and took advantage of the resources, leaving Africa with only poverty and bloodshed.
One of the biggest issues colonialism set on Africa that most people are not aware of or overlook, is that the colonizing countries did not spare a thought for the intricate loyalties and enemies between the different ethnic groups, shoving them together arbitrarily into countries. This caused a lack of cohesion within these new countries, which still causes problems today.
Colonialism and post-colonial actions have really taken their toll on Africa. Imperial powers brought over weapons, diseases, and agricultural practices that were very harmful to the native peoples and the native wild life. Even after countries relinquished their colonies, many of the countries in Africa were left with crippling poverty and destabilized governments.
Blaming the past is always a method that encourages weakness. The African nations receive billions in aid yearly. It is time to walk back this blame the past attitude. The African nations need to create the type of society that will succeed. The present system of aid just weakens them.
Short and simple. Africa blaming colonization as their problems is like the USA blaming Britain for the civil war. As time passes by African countries will eventually be able to handle themselves but being so far behind for modern countries today will probably prevent them to complete catch up. #USA
Never in history have the powers of Africa rivaled those of of the Arabs, asians, or europeans. All large african powers had large cultural, genetic, and technological "trade" with other already established arab powers. Plenty of areas in Africa have never gotten to stone construction, despite being located in very resource rich areas.
Africa is doing poorly for the same reasons black Americans are doing poorly. Their IQ averages are lower than other races, and they have higher average testosterone levels than whites. This is why Africa is predisposed toward violence and failure, while every other continent in the world has relatively high technological, cultural, and economic achievement.
Many countries have been colonized throughout the centuries. They have also inevitably gained their freedom and developed responsible, progressive social structues. The African continent, however, largely consists of countries that have been unsuccessful in doing this. This wasn't caused by colonialism, but by the type of leaders and their resistance to assimilation to the conquerors' ways of life.
