Passage B The miserable fate of Enron's employees will be a landmark in business history, one of those awful events that everyone agrees must never be allowed to happen again. This urge is understandable and noble: thousands have lost virtually all their retirement savings with the demise of Enron stock. But making sure it never happens again may not be possible, because the sudden impoverishment of those Enron workers represents something even larger than it seems. It's the latest turn in the unwinding of one of the most audacious promises of the 20th century. The promise was assured economic security—even comfort—for essentially everyone in the developed world. With the explosion of wealth, that began in the 19th century it became possible to think about a possibility no one had dared to dream before. The fear at the center of daily living since caveman days—lack of food, warmth, shelter—would at last lose its power to terrify, That remarkable promise became reality in many ways. Governments created welfare systems for anyone in need and separate programs for the elderly (Social Security in the U. S. ). Labour unions promised not only better pay for workers but also pensions for retirees. Giant corporations came into being and offered the possibility—in some cases the promise—of lifetime employment plus guaranteed pensions? The cumulative effect was a fundamental change in how millions of people approached life itself, a reversal of attitude that most rank as one of the largest in human history. For millennia the average person's stance toward providing for himself had been. Ultimately I'm on my own. Now it became, ultimately I'll be taken care of. The early hints that this promise might be broken on a large scale came in the 1980s. U. S. business had become uncompetitive globally and began restructuring massively, with huge Layoffs. The trend accelerated in the 1990s as the bastions of corporate welfare faced reality. IBM ended its no-layoff policy. AT but that could be regarded as a freebie, since nothing compels a company to match employee contributions at all. At least two special features complicate the Enron case. First, some shareholders charge top management with illegally covering up the company's problems, prompting investors to hang on when they should have sold. Second, Enron's 401(k) accounts were locked while the company changed plan administrators in October, when the stock was falling, so employees could not have closed their accounts if they wanted to. But by far the largest cause of this human tragedy is that thousands of employees were heavily overweighed in Enron stock. Many had placed 100% of their 401(k) assets in the stock rather than in the 18 other investment options they were offered. Of course that wasn't prudent, but it's what some of them did. The Enron employees' retirement disaster is part of the larger trend away from guaranteed economic security. That's why preventing such a thing from ever happening again may be impossible. The huge attitudinal shift to I'll-be-taken-care-of took at least a generation. The shift back may take just as long. It won't be complete until a new generation of employees see assured economic comfort as a 20th-century quirk, and understand not just intellectually but in their bones that, like most people in most times and places, they're on their own.
