This document discusses corporate ethics issues and scandals in various industries throughout history such as the meatpacking industry in the early 1900s, Enron in 2001, and more recently in the insurance industry. It provides examples of ethical issues like executive greed, accounting fraud, lack of transparency, and conflicts of interest that were common factors. The document also discusses the roles of regulators in failing to prevent these issues and provides conclusions that regulated industries with a lack of checks and balances are prone to such scandals. It notes Eliot Spitzer's investigations into the insurance industry in the early 2000s that uncovered bid rigging and lack of disclosure.
