Enron was great at bookkeeping. The sacrosanct part? Not so much. It turns out that when you don’t actually own anything or move anything or add value to anything, your sole income comes from what is in your ledger. Enron got really good at moving things on paper, “adding value” on paper to simulate income. They were so good that many believed Enron was the wave of the future, and so bought in. At its peak, Enron was the United States’ seventh most valuable publicly traded company.
