1. The end of colonialism.
Yep I'm a rascist but in 1900 around 13% of the worlds wealth was invested in countries that are called the third world. By 1997 this had fallen to less than 5%. You need capital to develop.
Colonial governments definitely invested a lot into infrastructure (ports, roads, dams, railroads, etc). Most of the large cities (and capitals) in Africa were founded by european traders, settlers and colonial administrators. It was an inevitable consequence of those being the only ones with the technical ability and resources, at the time, to built these structures.
Renaming cities after independence does not change any of that, but it was a cheap expedient used by the new african rulers to deny this past investment and pretend that their new countries owed nothing to the colonial past. In this attitude one can start to understand why the post-independence was usually disastrous: the changers got political capital out of of promoting wasteful and very often directly destructive change. Not content with a staged transfer of power, they wanted everything immediately, and most of what they got quickly went to waste.
But in this the power hunger of the new african rulers is as much to blame as the obstinate possessiveness of the colonial rulers who would have an exploitative system last forever, for their own benefit, and resisted gradual change.
2. Lack of effective laws/Government inefficenciy.
Weak despotic and idiotic rulers. Foreign aid has been pissed up against the wall. Zimbabwe anyone.
Actually, the despotic rulers were not weak. Despotism worked, where democracy failed, and the reason for that is the structure of african societies at the time of independence. Most of the population was illiterate and their political participation was structured through local strongmen and under traditional tribal divisions.
Democracy cannot work under such conditions.
3. Over reliance on cash crops. Reasonably monior factor as other countries also export a single crop or at least diversify their crops.
Not true. how can one have "over-reliance" on what is available? They had to start by exploiting those cash crops, because that was what they had. Only after building capital and/or attracting foreign investment on favorable terms could they diversify. And let's be realistic: foreign capital would not invest in Africa for its highly qualified labour... nor be directed to industrial production because the consumer markets around were weak and export markers were not open until the 1990s. So, foreign investment went mostly to "cash crops" and mining. The path towards diversification available to the new african states was narrow: carefully build capital for internal investment, but also promote internal markets for industrial production, meaning that the wealth from the "cash crops" had to be widely distributed among the population. But this slows the buildup of capital for investment. So this process necessarily had to be
slow. Have a civil war, or foreign invasion, or corrupt government, during it and the progress of many years of hard work is suddenly lost!
4. Rapid population growth exceeding growth in GDP. Asian tiger countries had a declining birthrate. Several Africcan countries have growth rates exceeding 3% which means their population doubles every 20 odd years and 17 years in the worst parts of Africa. Think Ethiopia and Rwanda has a population density exceeding alot of Europe.
Not all of africa went through population explosions. Not were these necessarily bad: more young population means more workers, should a state be able to take advantage of their labour. Ethiopia, for example, still manages to export food, the causes for its troubles must be found elsewhere.
5. Less developed to begin with even in the years before colonialism. Jared Diamond is kinda right. Alot of the Asian territiories were rule by Japan which invested heavily in Korea and Taiwn while the British invested in Hong Kong and Singapore. Infrastructure like roads, ports and airfieds were better developed.
This is true, but the lack of development was
social, not infrastructural. And that's way more difficult to quickly overcome.
6. War. WW2 and the Vietnam war pumped billions into Asia in addition to things like airfieds being built. Africa avoided the fighting but also avoided the economic benefit for the post war recovery.
I know that they had plenty of wars. And yes, wars did improve infrastructure in Africa. Angola, for example, got a large investment in paved roads during the 1960s as a way to avoid road mines, and this after decades of colonial neglect.
