Why is Oprah shutting down her elite girls' school?

US talk-show host Oprah Winfrey has announced that the school for underprivileged girls she established in South Africa nearly twenty years ago will close. The institution, which was launched to support girls from disadvantaged backgrounds, is scheduled to cease operations by the end of next year. This decision marks the conclusion of the educational project that Winfrey set up two decades ago to provide opportunities for girls within the South African region.
