In this photo taken Thursday, June 7, 2012, Colleen Knaggs, 18, talks about her fruitless efforts to find a summer job, from her home in Flagstaff, Ariz. Instead, Knaggs will be babysitting her younger brother, Matthew Knaggs, 10,  right. Once a rite of passage to adulthood, summer jobs for teens are disappearing. Fewer than 3 in 10 American teenagers now hold such positions as running cash registers, mowing lawns or busing tables in the months from June to August. The decline has been particularly sharp since 2000, with employment for the 16-19-year olds falling to the lowest level since World War II.   (AP Photo/Felicia Fonseca)
