Marriage is still a popular institution in the United States, but divorce is becoming almostas “popular”. Nevertheless, most American people get married at the present time. Fifty percentof American marriages end in divorce. However, four out of five divorced people do not staysingle. They get married a second time to new partners. Sociologists tell us that in the nextcentury, most American people will marry three or four times in one lifetime. Alvin Toffler,an American sociologist, calls this new social form “serial marriages”. In his new bookFortune Shock, Toffler gives many reasons for this change in American marriage. Inmodern society, people’s lives don’t stay the same for very long. Americans frequently change
their jobs, their homes, and their circle of friends. So, the person who was a good husband orwife ten years ago is sometimes not as good ten years later. After some years of marriage, ahusband and wife can feel that their lives have become very different, and they don’t share thesame interests any more. For this reason, Toffler says, people in the 21st century will not planto marry only one person for an entire lifetime. They will plan to stay married to one personfor perhaps five or ten years, and then marry another. Most Americans will expect tohave a “marriage career” that includes three or four marriages.
