Twenties are not preparing them to take on adult responsibilities and parents do not necessarily want them to. “It can sometimes be difficult to determine how much a child doesn't really want to grow up and how much a parent doesn't really want to let go” (Henig). Psychologist Jennifer Lynn Tanner says psychological development in adulthood can lead to better decisions later in life because they have more time to think about the future and explore their options (Henig). In the United States and other developed countries, adolescence most often occurs among young adult children of privileged parents because financial support is necessary. Arnett argues that it is not just the privileged who experience emerging adulthood, it is universal. The emergence of adulthood also happens to people from disadvantaged backgrounds, it is the opportunity for a new start in life (Henig). Conversely, in third world countries, children have to grow up quickly, so they barely experience adolescence and generally do not experience emerging adulthood (Henig). An example of prolonged adolescence is “a 30-year-old who sees part of his rent and bills covered by his parents, constantly enrolls in colleges or universities in search of additional degrees or qualifications, is single, without children.”
