pay-for
n.— «The Democrats’ new pay-as-you-go budget regimen means that lawmakers who want to spend more on one program have to either cut another or raise taxes to pay for it. Similarly, if they want to cut taxes, they must fund the cut by trimming programs or raising other taxes to make up the difference. Those budgetary offsets are called pay-fors—a new Washington buzzword striking fear in the hearts of special interests.» —“New Math on Hill, Scramble on K Street” by Jeffrey H.
