"A 2006 American Sociological Review study ("Social Isolation in America: Changes in Core Discussion Networks over Two Decades") reported that, in 2004, 25 percent of Americans did not have a single confidant. (In 1985, 10 percent of Americans reported not having a single confidant.) Sociologist Robert Putnam, in his 2000 book, Bowling Alone, describes how social connectedness is disappearing in virtually every aspect of U.S. life. For example, there has been a significant decrease in face-to-face contact with neighbors and friends due to suburbanization, commuting, electronic entertainment, time and money pressures and other variables created by governmental-corporate policies. And union activities and other formal or informal ways that people give each other the support necessary to resist oppression have also decreased."
