Hmm. South Africa is like a nation-sized Detroit. It was pretty much a garden spot when the whites ran it, and now it's turning into a sewer rapidly. Which country in Africa functions at the level of the most dysfunctional country in Europe, say Portugal or Greece? None, really.
The fault of Colonialism? India was run by the Brits for far longer than Nigeria, so were Canada and New Zealand.
The Caribbean? Crime-filled, violent, poor. I spent a week working in Jamaica recently. Good people there, but a pretty dysfunctional society.
I'm not as sure as you that the problems are limited to blacks in the USA, though they may be worse than some other countries, they are probably a lot better than some others.
Here's Liberia's recent history. If you went through the other 40 odd African countries many would be quite similar. A few bettter, a few, much worse. From WIkipedia:
On April 12, 1980, a military coup led by Master Sergeant Samuel Doe of the Krahn ethnic group overthrew and killed President William R. Tolbert, Jr.. Doe and the other plotters later executed a majority of Tolbert's cabinet and other Americo-Liberian government officials and True Whig Party members.[17] The coup leaders formed the People's Redemption Council (PRC) to govern the country.[17] A strategic Cold War ally, Doe received significant financial backing from the United States while critics condemned the PRC for corruption and political repression.[17] After the country adopted a new constitution in 1985, Doe was elected president in subsequent elections that were internationally condemned as fraudulent.[17] On November 12, 1985, a failed counter-coup was launched by Thomas Quiwonkpa, whose soldiers briefly occupied the national radio station.[18] Government repression intensified in response, as Doe's troops executed members of the Gio and Mano ethnic groups in Nimba County.[18]The National Patriotic Front of Liberia, a rebel group led by Charles Taylor, launched an insurrection in December 1989 against Doe's government with the backing of neighboring countries such as Burkina Faso and Côte d'Ivoire, triggering the First Liberian Civil War.[19] By September 1990, Doe's forces controlled only a small area just outside the capital, and Doe was captured and executed that month by rebel forces.[20] The rebels soon split into various factions fighting one another, and the Economic Community Monitoring Group under the Economic Community of West African States organized a military task force to intervene in the crisis.[20] From 1989 to 1996 one of Africa's bloodiest civil wars ensued, claiming the lives of more than 200,000 Liberians and displacing a million others into refugee camps in neighboring countries.[13] A peace deal between warring parties was reached in 1995 leading to Taylor's election as president in 1997.[20]
Under Taylor's leadership, Liberia became internationally known as a pariah state due to the use of blood diamonds and illegal timber exports to fund the Revolutionary United Front in the Sierra Leone Civil War.[21] The Second Liberian Civil War began in 1999 when Liberians United for Reconciliation and Democracy, a rebel group based in the northwest of the country, launched an armed insurrection against Taylor.[22] In March 2003, a second rebel group, Movement for Democracy in Liberia, began launching attacks against Taylor from the southeast.[22] Peace talks between the factions began in Accra in June of that year, and Taylor was indicted by the Special Court for Sierra Leone for crimes against humanity that same month.[21] By July 2003, the rebels had launched an assault on Monrovia.[23] Under heavy pressure from the international community and the domestic Women of Liberia Mass Action for Peace movement,[24] Taylor resigned in August and went into exile in Nigeria,[25] and a peace deal was signed later that month.[26] The United Nations Mission in Liberia began arriving in September 2003 to provide security and monitor the peace accord,[27] and an interim government took power the following October.[28]
The subsequent 2005 elections were internationally regarded as the most free and fair in Liberian history.[29] Ellen Johnson Sirleaf, a Harvard-trained economist and former Minister of Finance, was elected as the first female president in Africa.[29] Upon her inauguration, Sirleaf requested the extradition of Taylor from Nigeria and immediately handed him over to the SCSL for trial in The Hague.[30][31] In 2006, the government established a Truth and Reconciliation Commission to address the causes and crimes of the civil war.[32]
I have no argument with your thesis. You rightly point out the decaying situation in South Africa. Has there been any worse political situation in Africa than that in Zimbabwe under Mugabe? Still, I do not think the average African (which I will not attempt to define) bears the same degree of self described status as a victim nor the sense of entitlement as do some Blacks in the US. I believe that this attitude has been taught to those Blacks in the US by now decades of liberal initiatives, numerous of which continue today. They have been told repetitively that they cannot compete without affirmative action, that they have been denied opportunities, and that there is little need for motivation to excel (athletics as a noted exception). The US government has, without malice of forethought I hope, actively promoted precisely the antithesis of the character so markedly demonstrated by Dr. Ben Carson. So, many carry the chip on their shoulders, the sense of entitlement, and perceived relative deprivation even when compared to a broad cross section of their peers. Today, this mindset often manifests itself through violence, which is further reinforced by the lack of serious consequences for those very actions.
