In the past, the large majority of Americans frowned at the idea of divorce. Furthermore, many people believed that getting a divorce was a luxury that only the rich could afford. Indeed, getting a divorce was very expensive. However, since so many people have begun to take a more casual view of marriage, it is interesting to note that the costs of getting a divorce are lower. In fact, wherever you go in the United States today, it is no unusual to see newspaper ads that pro vide information on how and where to get a cheap divorce.
Hollywood has always been known as the divorce capital of the world. The divorce rate among the movie stars is so high that it is difficult to know who is married to whom. Today, many movie stars change husbands and wives as though they were changing clothes. Until marriage again becomes a serious and important part of people's lives, we will probably continue to see a high rate of divorce.
