When Vance Packard published The Status Seekers in 1959, abortion was still illegal in the United States.  While there were other things about present-day life in America that did not exist in Mr. Packard's era, one of the many points in his book that is still relevant today is the topic of teenage pregnancy.  After extensive research, Mr. Packard concluded that youngsters who do not envision bright, hopeful futures for themselves are the most likely to find themselves dealing with teenage pregnancies.  A 2004 study concluded an additional factor:  children and teens who grow up in dysfunctional families are also the most likely to become pregnant or impregnate someone while they are still in their teens.
