Michael Oxley, a former Republican congressman from Ohio, died this morning at 71. His family says his death was the result of lung cancer — though they add that he was not a smoker.

Rep. Oxley's name is plenty familiar to anybody who works in finance. The Sarbanes-Oxley Act of 2002 governs almost every aspect of a company's financial reporting and accounting practices, and people in the industry often complain about the cost of complying with all the reporting rules. Some say SOX — as the act Oxley co-authored with Sen. Paul Sarbanes, D-Md., is called inside the financial industry — is driving companies to the simpler regulatory climates of overseas markets.

But what's often forgotten is why Sarbanes-Oxley was passed. Before the financial crisis of 2008, there was the the dot-com implosion of 2000, and the high-profile fraud revealed by the collapse of Enron and the alleged complicity of its auditing company, the late Arthur Andersen.

As Oxley recalled five years later, there was intense pressure on Congress to reform corporate accounting in America.

As chairman of the House Financial Services Committee, he said he barely could risk walking onto the House floor, because he would be "besieged" by colleagues who'd just come back from their districts, where their constituents had demanded reform.

In retrospect, he came to believe that this "white-hot political response" was a result of the fact that Americans had spent the previous generation becoming a "nation of investors," as pensions were replaced by 401(k) retirement plans.

"Those people intuitively understood that that was their money," he said.

This "democratization" of Wall Street was something the financial industry had long been pushing for — and it got what it wanted, as 401(k)s became the new normal.
