There are many arguments about why unemployment remains so stubbornly high. Some explain that because the economy is weak employers are afraid to grow and reluctant to hire. Others have argued that the economy is facing stagnation and a failure of innovation, especially relative to booming economies in Asia and India. For educators, the "skills gap" explanation has been the most pertinent. This posits that employers now require higher skill levels from their workers and education is not providing what is needed. Consequently too many people are simply unprepared for work in the 21st Century.
