I think this is part of the problem in Africa, working hard, studying are seen as bad white traits.
You literally have no idea about Africa if you make that kind of statement.
It's a bit anecdotal, but I know several people (about 1/2 of them "white/mixed") who grew up in Kenya, South Africa, and Nigeria. According to them, most people in Africa don't even think about "whites". The biggest problems in Africa today are corruption and war. There are plenty of smart people in most countries there, but they have no access to good schools or jobs. Given the economic situation, many have to work very hard just to put food on the table. Everyone they know seems to want to send their kids to the best school they can (which is usually private) and they try to get their kids to study as much as they can.
The problem is that because of the huge human displacement in Africa (economic, war, etc), there are lots of young kids where their best option is to join a war-gang. This is a sad development, but not because that working hard and studying is a bad white trait.
In my estimation (talking to people I know who live in various places around the world, Africa, Asia, India, Western Europe, South America), this anti-intellectual attitude is primarily an American phenomena (black, white, Asian, it doesn't matter). I don't think you see this in other areas of the world as much as you see it here.
