I think in Enron and Theranos cases, there were specific actual crimes happening. Like lying in the published information that's influencing the stock market. Or falsifying you financial records. Things specifically forbidden and labeled as criminal.
Not a thing that is so non-specific (in it's criminality) that you have to label it wire-fraud or mail-fraud (whatever that is) to even have a chance at making it look like actual crime, not just immoral thing he did that could harm his employer (but it's hard to tell to what extent it actually did).
Do you try to straw man me into position "all white collar crimes shouldn't be crimes"?
