Based on the assumption that economic security is fundamental to children's well-being, this guide outlines the National Commission on Children's recommendations for making income security of families a national priority for the 1990s and indicates how the recommendations can be implemented. The Commission's income security package comprises six elements: (1) creation of a $1,000 refundable tax credit for all children through age 18 and elimination of the personal exemption for children to partially offset the costs; (2) provision of the Earned Income Tax Credit as an incentive for low-income parents to enter the paid work force; (3) establishment of a national demonstration project to design and test a plan that will enhance child support enforcement and create a government-insured minimum benefit when absent parents do not meet their support obligations; (4) provision of essential transitional supports and services to aid families moving from welfare to work; (5) provision of community employment opportunities to poor parents who are willing and able to work but unable to find a job; and (6) reorientation of the Aid to Families with Dependent Children (AFDC) as short-term income support for families experiencing unemployment, disability, or other economic hardship. This guide discusses ways to implement the first five elements of the package, assuming that the last goal will result from effective implementation of these elements. (AC)
