A close inspection of approved and pending state waiver programs suggests that the expansion of Medicaid provides a new means of social control over the poor and uninsured. Changes in the structure and financing of state Medicaid programs, like work requirements and time limits on eligibility, limit the appeal of publicly funded medical insurance. In addition, the social construction of the target population legitimizes the imposition of restrictive health care arrangements for poor women that would be politically indefensible if applied to the general population or to "deserving" subgroups with the population (e.g., retirees).Recent changes in state Medicaid programs have brought states to the forefront of national efforts to increase access to health care while controlling costs. In particular, the growth of managed care for Medicaid beneficiaries has produced a growing body of research on the organization and delivery of health care to the poor. To date, however, most studies have been narrowly defined in terms of program organization and financing; few scholars have explored the political and social implications of these sweeping changes for the poor. As an instrument of social policy, the growth of Medicaid managed care can be viewed as state governments' latest effort to control the behavior of the poor through restrictive social welfare policies. From this vantage point, recent changes have less to do with improving the coordination of health care services and more to do with lessening the appeal of means-tested medical assistance.
