The Liberian government received a report on the various for-profit corporations providing schooling. The bottom line: scores went up, but the cost of services varied dramatically. The most expensive of all the providers was Bridge International Academies, the for-profit corporation that is funded by Bill Gates, Mark Zuckerberg, and other luminaries of the tech sector. Their costs were so much higher than that of any other service that it is doubtful that they are sustainable.

The so-called Partnership schools received double the funding of the public schools: $100 instead of only $50. And the Ministry of Education made sure that the Partnership schools were well-supplied with teachers, including the best-trained.

Four of the networks managed to produce results for less than $100 per pupil. Bridge, however, cost more than $1,000 per pupil, a figure dramatically higher than any other network, and their results were not markedly better.

Will Nicholas Kristof reconsider his fulsome praise for Bridge International Academies? The skeptics were right to be concerned about sustainability and scalability. Why did the billionaires think it was a good idea to try to turn a profit off the backs of the poorest people in the world? These Silicon Valley geniuses may be good at selling product, but they are not very good at creating or providing an education system.
