As McKinsey & Co. pointed out last month in its study on the global demand for high-skilled labor, the percentage of labor-intensive, or low-skilled assembly and factory line jobs declined by half since the 1970s;  low-skilled jobs as a percentage of all manufacturing positions declined by 29 percent, while the percentage of manufacturing jobs in capital- and knowledge-intensive areas – those requiring strong math, science, and computer language skills – have and will continue to increase.
