Workers in the informal sector are more difficult to provide for. Some have done so through public health services targeted to the poor. This is neither desirable nor efficient, generally resulting in a health care system in which poor people receive inferior quality services, often in public facilities, while the nonpoor get better health care services from the private sector. Health services targeted to the poor generally remain underfunded partly because the more powerful people who are not poor have no stake in making the system better.
