Talking about the obesity problem in Africa and the redistribution of farm land in Zimbabwe:
A: South Africa has had more than enough food for its people for a while.
Me: Yeah, because it's a bunch of white people.
A: Well, Zimbabwe did too, before the redistribution of farm land. Of course, the farms were owned by white people.
Me: Well, white people know what to do with a farm - get black people to work it.
