I think  a good chunk of the anger in the USA is the quality of the jobs, as well as the number.  Large amounts of current jobs are minimum wage, limited hours jobs.  Manufacturing jobs paid well.  That's what is irritating so many right now.  Unemployment rates aren't the only story.  If a person has to take on 2-3 jobs to make ends meet, they aren't going to be real happy about the fact that the unemployment rate is low.
