Write down arguments in favor of implementing the user charge/fee you chose as though you are trying to convince an elected official to vote for it on the merits. Saying you can't think of any arguments in favor is not an acceptable answer. Maybe you think that, in and of itself or as an alternative to some other general tax, the charge/fee makes sense and appropriately addresses one or more of the competing characteristics/concepts usually used to analyze taxes: (adequate, progressive, exportable, diversified, benefit correlation, discouraging or encouraging specific consumption to achieve a social goal, simplicity, neutrality, competitiveness, etc) or perhaps it meets some other goal. if implementing a $3 charge (copay) for any Medicaid recipient every time he or she has his or her Medicaid prescription filled, or refilled, by a pharmacy. No fee (copay) had existed previously. The copay will recover about 2% of the cost of Medicaid prescriptions.
