The last time anyone attempted to “modernize” auditor independence rules it was the Securities and Exchange Commission, in 2000, before the Enron failure and Arthur Andersen’s demise, as a result of the growing concern that firms increasing focus on consulting was distracting them for their core purpose, auditing. The Big Four firms are now opportunistically lobbying to go back in time, before Enron, when the industry was self-regulated and mostly left alone, able to have as many conflicts of interest as their powerful public clients would allow.
