Of course it would be good for them. Teaching in Africa was one of the best things I ever did. But our example seems to have counted for very little. My Malawian friend's children are of course working in the United States and Britain. It does not occur to anyone to encourage Africans themselves to volunteer in the same way that foreigners have done for decades. There are plenty of educated and capable young adults in Africa who would make a much greater difference than Peace Corps workers.

Africa is a lovely place -- much lovelier, more peaceful and more resilient and, if not prosperous, innately more self-sufficient than it is usually portrayed. But because Africa seems unfinished and so different from the rest of the world, a landscape on which a person can sketch a new personality, it attracts mythomaniacs, people who wish to convince the world of their worth. Such people come in all forms and they loom large. White celebrities busy-bodying in Africa loom especially large. Watching Brad Pitt and Angelina Jolie recently in Ethiopia, cuddling African children and lecturing the world on charity, the image that immediately sprang to my mind was Tarzan and Jane.

Bono, in his role as Mrs. Jellyby in a 10-gallon hat, not only believes that he has the solution to Africa's ills, he is also shouting so loud that other people seem to trust his answers. He traveled in 2002 to Africa with former Treasury Secretary Paul O'Neill, urging debt forgiveness. He recently had lunch at the White House, where he expounded upon the "more money" platform and how African countries are uniquely futile.

But are they? Had Bono looked closely at Malawi he would have seen an earlier incarnation of his own Ireland. Both countries were characterized for centuries by famine, religious strife, infighting, unruly families, hubristic clan chiefs, malnutrition, failed crops, ancient orthodoxies, dental problems and fickle weather. Malawi had a similar sense of grievance, was also colonized by absentee British landlords and was priest-ridden, too.

Just a few years ago you couldn't buy condoms legally in Ireland, nor could you get a divorce, though (just like in Malawi) buckets of beer were easily available and unruly crapulosities a national curse. Ireland, that island of inaction, in Joyce's words, "the old sow that eats herfarrow," was the Malawi of Europe, and for many identical reasons, its main export being immigrants.

It is a melancholy thought that it is easier for many Africans to travel to New York or London than to their own hinterlands. Much of northern Kenya is a no-go area; there is hardly a road to the town of Moyale, on the Ethiopian border, where I found only skinny camels and roving bandits. Western Zambia is off the map, southern Malawi is terra incognita, northern Mozambique is still a sea of land mines. But it is pretty easy to leave Africa. A recent World Bank study has confirmed that the emigration to the West of skilled people from small to medium-sized countries in Africa has been disastrous.

Africa has no real shortage of capable people -- or even of money. The patronizing attention of donors has done violence to Africa's belief in itself, but even in the absence of responsible leadership, Africans themselves have proven how resilient they can be -- something they never get credit for. Again, Ireland may be the model for an answer. After centuries of wishing themselves onto other countries, the Irish found that education, rational government, people staying put, and simple diligence could turn Ireland from an economic basket case into a prosperous nation. In a word -- are you listening, Mr. Hewson? -- the Irish have proved that there is something to be said for staying home.
