Passage 3　　The greatest impact on the family over the last 50 years has been the changing role of the wife. These changes have affected not only her life but also that of her husband and children. (1) The family has changed from an economically defined unit under the authority of the father and having minimal interpersonal emotional ties to a unit with strong emotional ties directed primarily by the mother to her husband and children. One important result was greater emotional and general psychological seclusion of the woman which clearly implied that the female role was culturally a secondary one.　　In recent decades it has become clear that for a distinct minority of American women the traditional mother role in the seclusion of the home is no longer acceptable. For many the family is of diminishing importance. The development of education for women has been a crucial factor in this change. Today, over 80 percent of all women complete four years of high school as compared to only 35 percent in 1940. This is related to the fact that marriage now occurs a year later for the average woman. The proportion of women aged 20 to 24 who are single increased from 28 percent in 1960 to 40 percent by the mid-1970s. (2) Child bearing is being postponed, so that compared to the 1960s, 10 percent fewer women bear their first Enid in the two years immediately following marriage. Furthermore, more women today remain childless. Work, older age at marriage, and fewer children are the basic changes that have taken place in women’s roles in recent years.　　The trend among women is toward increased education, and this is linked to other role changes. (3) The higher a woman’s educational attainment, the more likely she is to work, to stay in the labor force longer, and to have more job opportunities available to her. This further suggests that when women are married their work has a great impact on their marriages. For example, since working wives contribute 25 to 40 percent of their total family income, their position as decision-makers in the family is usually strengthened. (4) Waits points out that the social trends towards increased education for women mean not only more work experience but also delayed marriage and decreased fertility. These changes, in turn, point the way toward even greater labor force participation throughout the life cycle.　　The number of women entering the work force is rapidly increasing. Women outnumber men in the total population by about 7 million. (5) When that is added to the fact that labor force participation of males is slowly declining because of the trend toward earlier retirement, “it may not be too long before one out of every two American workers is a woman.”

The On-going Debate over Healthcare Reform　　It seems that the government’s so-called Blue Ribbon Commission has already decided what plan it will propose without undertaking any public consultation and is now merely engaged in a PR campaign to convince us they have the answer.　　This seems a little head over heels to us. Since it is our money and our health that is in question, shouldn’t we have been consulted at the break about which way we want to go?　　There are several models to achieve healthcare reform, and not all of them require us to hand more money over to keep government bureaucrats in big offices. Purely private healthcare may have big problems—but so does the socialised medicine the commission is recommending.　　For example, Canada’s universal system of socialised medicine is now busily engaged in transferring costs from the public to the private sector… by reducing covered expenses, by de-insuring some expenses and so on.　　Medical authorities are on record as saying that in an effort to manage costs, hospital stays are being shortened (or even dispensed with altogether).　　So while we in the Bahamas are citing universal ‘free’ health care as the answer to our problems, in Canada there is an uncoordinated scramble by the public system to reduce and offload the effects of rising health care costs. And we won’t even mention the litany of complaints from users who have to wait for poor service.　　But what mostly concerns us about the Blue Ribbon Commission is that they have plumped for social health insurance without determining the cost of their recommended programmer, or of the alternatives.　　And they do not seem to have taken into account the impact this plan will have on the fiscal deficit or on our individual pockets. Apparently, the position is that whatever the cost, this is the plan that will be presented to parliament.　　An initiative so far-reaching and so potentially damaging to our economy, should require more careful assessment of the alternatives in public. There is always more than one way to skin a cat. And we do not believe that a small group of consultants constitutes ‘the public’.
