The domestic economy and international economies are indistinguishable except in a political, social, cultural, and psychological sense. Also, these nations have given priority to performance on the world economy over domestic economic performance. Huge welfare bureaucracies have been created but have failed to measure up to the problem. The second reason for suggesting the viability of a social sector has to do with the number of volunteers who work in social organizations. The 90 million volunteers in the United States, working an average of three hours per week, are predicted to increase to 120 million volunteers donating an average of five hours per week.
Churches are the largest single group of organizations within the non-profit sector.
Drucker cites the Salvation Army, Alcoholics Anonymous, and private secondary schools as examples of the effectiveness of non-profit organizations in addressing social problems. Vouchers could be given to move students from public to private schools. For the non-profits to reach their potential they need to become better at managing themselves and raising money, which will have to come from greatly increased giving of personal income. Drucker does not advocate the development of partnerships between non-profit and private sector organizations for functions vital to businesses, such as training and job placement. Government, in Drucker's view, needs to assume a more limited role.
