Odd because we didn't experience an increase in violent crime during the recession, in fact it continued to decrease. How many of those studies look at data after the great mid century crime wave had settled? As for evidence that jobs and prison prevent recidivism (or crime in general), assuming they do to some degree, how much more or less effective are they than therapy?
