Business based Marshall Plan for Africa?

Glenn Hubbard writes in FP:

In all rich countries, the development of a thriving business sector came before physical and social infrastructure. In fact, the Marshall Plan worked because it made loans to European businesses first, which then paid money back into a national pot to fund commercial infrastructure. Africa has already demonstrated its potential for achieving the same. In telecommunications, for example, Africa has become the first continent where cell phones outnumber land lines, thanks to many excellent African entrepreneurs (and the many terrible government land-line systems). Besides, businesses that have a stake in the maintenance and viability of a given project are bound to be far more apt at building and maintaining infrastructure than aid agencies, which have been trying to do it and failing for the past 40 years. Given that many parts of the continent still lack basic roads, water systems, electrical grids, and more, isn't it time to retire the current, aid-driven system?
