“He then asked: "Why is US social capital eroding?" and discussed several possible causes.[1] He believed that the "movement of women into the workforce"[1] and other demographic changes had an impact on the number of individuals engaging in civic associations. He also discussed the "re-potting hypothesis", that people become less engaged when they frequently move towns, but found that Americans actually moved towns less frequently than in previous decades.[1][3] He did suggest that suburbanization, economics and time pressures had some effect, though he noted that average working hours had shortened. He concluded the main cause was technology "individualizing" people's leisure time via television and the Internet, suspecting that "virtual reality helmets" would carry this further in the future.[1]” Via Wikipedia
