"The counter argument might be that CRM has done little or nothing to improve accident rates in non-private flying. Does anyone know whether there is any evidence to suggest that CRM has had a measurable benefit anywhere?"
Over the last 20 years, accidents related to human factors have reduced by around 40%. I believe that was from the Flight Safety Foundation.
When I was a TRE I refused to test private owners unless they had a certain degree of humility. The big problem with them (and you don't have to be rich, necessarily) is impatience. I have found that that is the first sign of anger.
