Bruce Bartlett's scat hing critique of Sarbanes-Oxley is available at NRO. Among other good points, he quotes someone familiar to readers of this blog:
Stephen Bainbridge, professor of corporate law at UCLA, thinks Sarbanes-Oxley was completely unnecessary. He says all economic booms inevitably breed their financial scandals. The scandals at Enron et al. would likely have occurred even if Sarbanes-Oxley had already been in effect. The scandals simply gave statists a new excuse to regulate business. ?Corporate scandals are always good news for big-government types,? Bainbridge notes.
