Medium-skill and high-skill workers, on the other hand, might be on the verge of a renaissance. The study predicts that employers will have 45 million more jobs than applicants for workers with secondary education and vocational training over the same time period. College graduates will also be in demand: McKinsey says we'll need 38 to 40 million more workers than are currently available.
"The polarization of incomes between high- and low-skill workers could become even more pronounced, slowing the advance in national living standards, and increasing public-sector burdens and social tensions. In some advanced economies, less-skilled workers could very well grow up poorer than their parents, in real terms," the study said.
The Institute advised developed countries to double the number of people receiving college and postgraduate degrees to help make up the shortfall -- not an easy fix in a time when college is more expensive than ever.
Even that might not be enough. Even if policy makers take this advice, 20 to 23 million low-skilled workers are in danger of permanent joblessness, according to the report. Currently, 6 percent of workers across the globe are unemployed, according to the International Labour Office.
