Family activities in modern society differ from labour in the market sector. Illich notices family activities are non-payment labour and Boulding notices family activities are characterized by ‘gift’ instead of exchange. These characters have been maintained by exclusin of utilitarian motivation and supply of emotional and moral motivation, instead market sector have been maitained by supply of utilitarian motivation and exclution of emotional and moral motivation. This division of motivational mechanism has supported the production and reproduction of the capitalist society. The recent family situation in advanced capitalist society is shaking this division system. The character of emotional motivation is changing moral motivation become weeker and utilitarian motivation is invasing family activities. Consequently, the case that sufficient activities of family isn't supplied and that family activities execute for the market sector increase in number. The government of capitalist states have noticed this motivational crisis in the family sector, and have intervened the family activities, but not successfully. I try to examine this process, examplifing the family policy in U. S. A..
