Moreover, any increase in spending on infrastructure or any revenue loss from tax reform should be offset elsewhere. For example, future growth in Social Security benefits or the home-mortgage-interest tax deduction could be scaled back for more affluent individuals, as progressive indexation, proposed by conservatives in the US, and the adjustment of mortgage-interest tax deductions in the United Kingdom, started during the Thatcher administration, attest.
此外，基础设施支出的任何增加或税收改革所导致的任何收入减少应该通过其他手段抵消。比如，丰裕个人的社会保障金或住房按揭利息税收抵扣应该减少，美国保守派所提出的的累进指数化（progressive indexation）和英国在撒切尔夫人执政时期所实施的按揭利息税收抵扣调整证实了这一点。
