I doubt it's the lack of adrenaline being the main driver for skirting away from "white collar" crime. More likely, the analytical and time consuming work required, and perpetrators who are much more likely to evade capture and/or sentencing, through usage of lawyers, accountants et al.

Also, the victims of wage theft are less likely to be "well connected" sponsors of political careers, while the victims of larceny are naturally more often business owners whom are more likely to have a "voice".
