Do our big accounting firms deserve some of the blame for the demise of a free press, and even democracy itself, in Russia? This thought first occurred to me when I stumbled on the fact that PricewaterhouseCoopers (PwC) is the accounting firm for Yukos, the huge, troubled Russian oil company. As has been reported, Yukos' principal owner is now in jail on massive tax-evasion charges, other corporate officers have fled the country to escape arrest, and the company's potential bankruptcy has helped push up the world price of oil to record highs. The plot thickened when I discovered that Yukos' ownership runs through a chain of tax havens, leading ultimately to a post-office box in tiny Gibraltar.
