To teach, train and retrain millions of people, online education is the only scalable option

[Commentary] It may be hard to believe in this era of social networking and telepresence video conferencing, but there is still a stigma attached to online education. Elite institutions do not want to dilute their brands by expanding the reach of their methodology using online channels. This is a mistake, a humongous lost opportunity, and one that needs to be revisited because an astoundingly large number of people in America need retraining and career makeovers right now. In India, China, Brazil and Indonesia, the sheer size of the populations suggests that nothing other than online education can meet the needs of billions of people hungry for an opportunity to learn and secure a passport out of poverty.
