It is funny, that small and even sometimes medium business owners go to jail over things like fraud, failure to pay taxes, even labor violations. I remember local instances being reported on in the our (thankfully still around) local paper.
Yet, if you are big enough, the government can barely muster the strength to issue a fine. Rarely to executives at big firms go to jail unless there was something Enron sized egregious happening
If true, we have a name for this, its called fraud. Little people like you and me go to prison for it.
