The Africans do put them to shame, and many despise American blacks for how they’ve sqyuandered opportunities they could only dream of back in Africa; while American blacks may attribute their shortcomings to racism (they often view Africans as “white” because of their command of the English language), they know that for whatever reason they do not have the skills to make the case to a company that hiring them would benefit the bottom line.
The fact that their feeble excuse holds no water doesn’t deter them from using that rather than admitting personal failure.
And that’s a “human” failing, not a “black” failing. I don’t know of any place in which white people are more cordial to black people than the USA. It’s probably going to take some big mutual disaster to end the pity party. (Obama might be it.)
