In US federal prisons, drug offenders make up over 40% of the total population, by very far the largest group. The next largest tracked category, "Weapons, Explosives, and Arson" is 23%. [0]
Granted, these are almost entirely US federal offenses, which have of course been flux throughout US history with respect to proper authority, and drug offenses have tended to grease the wheels of jurisprudence so as to be regarded constitutional (albeit with a very inconsistent set of underlying principles). Murder for example is not generally a violation of federal law absent (a fairly long list of) special circumstances.
I do not believe there is any state where the number of people incarcerated for fraud convictions is in the same order of magnitude as drug convictions. In Ohio, where this story takes place, drug offenders are about 14% of the population while "fraudsters" are about 1%.
I think it's pretty reasonable to assert that a significant portion of prisons in the USA are convicted of offenses that are not easy to understand as a moral affront to society or an infringement on the rights of anyone else.
