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 programmes 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 premise — 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 it's no-layoff policy. AT＆T fired thousands, many of whom found such a thing simply incomprehensible, and a few of whom killed themselves. The other supposed guarantors of our economic security were also in decline. Labour-union membership and power fell to their lowest levels in decades. President Clinton signed a historic bill scaling back welfare. Americans realized that Social Security won't provide social security for any of us.
A less visible but equally significant trend affected pensions. To make costs easier to control, companies moved away from defined benefit pension plans, which obligate them to pay out specified amounts years in the future, to defined contribution plans, which specify only how much goes into the play today. The most common type of defined-contribution plan is the 401 (k). The significance of The 401 (k) is that it puts most of the responsibility for a person's economic fate back on the employee. Within limits the employee must decide how much goes into the plan each year and how it gets invested— the two factors that will determine how much it's worth when the employee retires.
Which brings us back to Enron？ Those billions of dollars in vaporized retirement savings went in employees' 401 (k) accounts. That is, the employees chose how much money to put into those accounts and then chose how to invest it. Enron matched a certain proportion of each employee's 401 (k) contribution with company stock, so everyone was going to end up with some Enron in his or her portfolio; 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 file company changed plan administrators in October, when the stock was fal
A．Because the company has gone bankrupt.
B．Because such events would never happen again,
C．Because many Enron workers lost their retirement savings.
D．Because it signifies a turning point in economic security.
