Employment is a structural issue. The fed is wrong in using it as a criteria for the end of QE. This is a mismatch between skills and what the economy demands. Too many have received college degrees in underemployed majors. Companies are doing more with less and the encouragement of the Obama administration to move more to food stamps and disability has created a dependency class of unemployables with no job skills and no experience.
Sources include the population ratio, labor force participation rate, and the employment rate.
