When 11% is a big problem

From the McKinsey Global Institute - - The World at Work: Jobs, Pay, and Skills for 3.5 Billion People.  This will be very interesting to watch - -

"90 million to 95 million more low-skill workers (those without college training in advanced economies or without even secondary education in developing economies) than employers will need, or 11 percent oversupply of such workers"

When employers have no need for "such" workers - - who does?
