And you played the devils advocate well but the reality is very different. As a former CEO I can tell you that there definitely are jail sentences possible for rather minor offenses (where I live, mind you) like not answering a letter by the government because you were busy. Granted, you do have to be very overwhelmed to not answer those for an extended period but it happens.
But its the same for small companies that male no profit as it is for multi billion dollar companies.
I suppose you get the problem here. We have always pinned it on the individual because fines are a corpos wet dream. Same readon why the country I live in has mostly fines for speeding (so it doesnt affect the rich).
So, mandatory jail sentences, increasing with the companies profit.
