What caused the higher unemployment rate?
Weak demand for goods and services, as a result of the recession and its aftermath, which results in weak demand for workers;
Mismatches between would-be employers’ needs and the skills or location of the unemployed;
Incentives for people to stay in the labor force and continue searching for work that result from extensions of unemployment insurance benefits; and
The erosion of unemployed workers’ skills and the belief of some employers that people who have been unemployed for a long time would be low-quality workers (a phenomenon sometimes called stigma).
I would have phrased the first two of these points differently. There are always jobs, though it depends on what price. The question is why people aren't taking the jobs that they can get.
