At the time, Arizona lawmakers and expansion advocates promised that expanding Medicaid would lower the uninsured rate, reduce uncompensated care costs, decrease the "hidden tax" on private insurance for uncompensated care, and save about $30 million a year in state funds.
These same promises — lower uninsured rate and reduced uncompensated care costs — are being made by those calling for Medicaid expansion in other states.
None of the promises came true. In fact, the opposite happened. Enrollment of parents was more than triple what was forecast, while enrollment of childless adults was more than double.
As a result, costs skyrocketed.
