What is the most outrageous corporate fraud case of the last thirty years?

A successful startup founder or the CEO of a mammoth corporation is our society's ideal. Yet so many of these figures turn out to be fraudsters. I'm launching a new series called Fake It Till You Make It exploring corporate fraud cases and what they can tell us about the state of the modern economy. But which scandal is the most heinous? The collapses of Enron or Lehman Brothers? Crypto/ETF rug pulls? Theranos' fake blood tests? Tell us which scam most sparks your outrage, and have lessons been learned?
