I personally don't understand what makes executives so special that they are exempted from the same sort of criminal proceeding the average Joe is faced with. By all accounts they hold these lofty positions precisely because they can (and should) be held responsible for their company's dirty deeds.

A fine is low stakes because the company more likely than not will have a way to recoup that loss. There is an obvious calculus to that which is practically a cliché to mention. A lawsuit just puts it on the people to succeed in civil proceedings at their own expense, over a potentially lengthy period of time.

Western countries like the UK and US tend to be quite soft on businesses engaging in practices that would land an unremarkable working class person in prison if they were caught doing the same.
