Behind the push for online learning

There's a reason Gates and the power philanthropists are pushing online education so hard and it has less to do with teaching and learning as it does with super profits. The Boston Consulting Group reports that the Internet accounted for $684 billion, or 4.7% of all U.S. economic activity in 2010. By way of comparison, the federal government, contributed $625 billion, or 4.3%, to the nation's output.

If it was considered its own separate industry, the Internet would also be larger than America's education, construction or agricultural sectors. -- CNN
