This unfortunately widely held belief is measurably wrong and reeks of all kinds of biases. White collar criminals are one of the categories most likely to reoffend. Recidivism is much higher in white collar criminals precisely due to the leniency they often experience and the powerful financial motives associated with these types of crimes.
For violent crime 38.9% of convicts were arrested for new crime within 3 years of release. White collar crime on the other hand had a 58.8% 3-year recidivism rate.
White collar crime poses systemic risks which violent crime doesn't to the same extent. It undermines confidence in institutions by creating corruption and waste, enriching few at the expense of many. When it becomes normalized and widespread this kind of crime can destroy a country's economic and political systems.
