a good book to read about this lack of prosecution is called "the chickenshit club" by Jesse Eisinger. In it the author explores prosecution paralysis brought on by a fear of destabilizing markets, and that this fear ultimately led to fines being preferred over jailtime. it also dives into the revolving door between prosecutors of these organizations and the organizations themselves, and the fact that no prosecutor wants a losing case on their record as it may adversely affect their chance of career success. Its also interesting to note from the book that a CEO fired from a company and indicted may continue to receive payments or parachutes from that company in order to fight government charges and keep quiet about improprieties, whereas other types of criminals see all assets frozen upon such criminal proceedings.
