The collapse of Enron, the largest bankruptcy in American history, has rung out a banner year for American business failures. In Europe, the fallout from the Swissair and Sabena insolvencies continues. In the current global slump, more companies are likely to go under. Now is a perfect time to reconsider how to handle such failures: let them sink, or give them a chance to swim

In America, bankruptcy has come to mean a second chance for bust businesses. The famous "Chapter 11" law aims to give a company time to get back on its feet, by shielding it from debt payments and prodding banks to negotiate with their debtor. It even allows an insolvent company to receive fresh finance after it goes bust. On the other side of the Atlantic, when companies stumble, almost as much effort is spent in fingering the guilty as in trying to salvage a viable business. British and French laws, for example, can make a failing company’s directors face criminal penalties and personal liability. Moreover, bankers have the power, at the first sign of trouble, to push a company into the arms of the receivers. Some modest changes are afoot, however. Britain is considering moves that would bring its rules closer to America’s. New laws in Germany should also make it easier to revive sick companies, although trade unions still have their say.

But even with the arrival of the euro and moves towards a single financial market, going bust in Europe is a strictly local affair. Long before America had a single currency, the American constitution provided uniform bankruptcy laws, observes Elizabeth Warren of the Harvard Law School. Europe’s patchwork of national laws, according to Bill Brandt of " Development Specialists", a consultancy, inhibits lending and makes it difficult to fix ailing firms.

Transatlantic insolvencies are even harder, as a Belgian-based software company, Lernout and Hauspie, discovered this year. Its American reorganization plan was thwarted by a Belgian judge, who ordered a sale of the firm’s assets. As the European Union inches toward greater harmonization, should it try to mimic America

Critics of Chapter 11 think not. They argue that America’s bankruptcy system is wasteful, lets failed managers go unpunished, and gives some companies an unfair advantage. In Chapter 11, admittedly, lawyers and advisers gobble up fees, but a recent study argues that the fees are no larger than those for most mergers and acquisitions. One common complaint, that managers enjoy the high life while creditors go begging, fails to stand up to the data from America’s previous wave of bankruptcies in the early 1990s. Stuart Gilson of the Harvard Business School found that more than two-thirds of top managers were ousted within two years of a bankruptcy filing. More troubling is that some American firms seem to enjoy second and third trips to bankruptcy court, cheekily termed Chapters 22 and 33. Some see this as evidence that, ton often, they use Chapter 11 to keep running. But there is more to the story.

The last paragraph is mainly()

A. to accuse the lawyers and advisers of making big money by helping those insolvent companies

B. to introduce the changes of the bankruptcy law—Chapter 11

C. to prove the accusation is groundless that the managers of bust businesses lead a comfortable life at the cost of creditors

D. to argue that the European Union should not follow the American example in their effort to revive sick companies
