The percentage of low-skilled manufacturing jobs continues to decline
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.

Manufacturing jobs just ain’t what they used to be
Many service jobs will become globalized piece work
We spend 80% of our classroom time on the skills needed for 10% of our jobs
Some Iowa students weigh in on what classes they need for 21st century jobs

It’s just easy and affordable for most companies to send low skilled jobs overseas. People need to really become more intelligent in the United States, we need to have a deeper focus on education as a country, then you will see both sectors rise.
