Maybe a better example is the tobacco companies. They were convicted of a 50 year conspiracy to mislead the public about the health dangers of smoking, an activity that has led to trillions of dollars in health care costs and the deaths of literally millions of people in that span (in the US alone). No one went to jail for this...the companies "just" had to pay a $200 billion dollar fine (global annual tobacco sales revenue is estimated at $500 billion).
