“…YellenÕs (1990) ethnography of !Kung suggests that wealth correlates with movement away from collectivist living, hoarding instead of gift-giving, and diminishing values of intimacy and interdependence. While cooperation can enhance public wealth, the rapid growth of wealth can result in defection from cooperative norms (Ball 1999) (Yang, 1996;Yang, 1988;Inglehart & Baker, 2000;Allen, et al, 2007). For instance, scholars have noted that economic growth in the United States correlates with a decline in conformity (Alwin, 1989;Bond & Smith, 1996), withdrawal from social groups and institutions (Glenn, 1987;Putnam, 2000), a rise in individualism (Roberts & Helson, 1997;Twenge & Campbell, 2001;Twenge & Campbell, 2008), narcissism , and a decreasing need for social approval (Twenge & Im, 2007).…”
