Dear Dr. Boli: I hear that some African countries are planning to stop the practice of allowing billionaires from other continents to come in and hunt rare wild animals for trophies. But how can they do that without ruining their own economies? What engine of revenue will they put in the place of the traditional safari? —Sincerely, Dr. Arvin Stanley, Prominent Economist.

Dear Sir: Dr. Boli has not been consulted by any of the governments in question. But if they were to consult him, he would have a suggestion ready to hand. They can allow the billionaires to come in as usual; but instead of being given guns and turned loose in game reserves to hunt lions and rhinoceroseses for so-called sport, they will be turned loose in the same reserves, and a certain number of local citizens in good standing will be given guns and allowed to hunt billionaires and keep whatever trophies they this acquire. This will be at least as exciting for the billionaires, and probably a great deal more so; and it will solve the problem from two points of view. We have too many billionaires and not enough cheetahs and wildebeests. It may seem cruel, but any ecologist will tell you that sometimes it is necessary to cull the herd.
