Last time I flew back from Johannesburg I sat with a few young men who were South African farmers. They were on their way to the US to work on our farms for half the year because we can't find enough Americans who are willing to do this work... AND because they were terrified to work farms in SA.
I also spent a couple weeks in Zimbabwe, which was once the breadbasket of Africa but where most farms are now fallow because no one left in the country knows how to farm.
