为慈善捐赠提供税收减免往往演变为富豪避税与资金闲置的工具。已故地产大亨谢尔登·索洛曾将大量名画捐赠给个人基金会以换取巨额减税，但其画廊每周仅开放一个多下午；埃隆·马斯克的基金会积累了超过140亿美元的免税资产却长期处于闲置状态，其2024年最大一笔3.7亿美元的赠款竟流向了其名下仅为十名幼童提供服务的SpaceX基地托儿项目。数据显示，2020年年收入超过50万美元的美国高收入家庭拿走了全美超过一半的慈善捐赠个人所得税减免额度；预计到2026年，仅美国因该项减税政策损失的财政收入就将超过700亿美元（相当于阿拉斯加州的GDP总量）。

自一战期间美国国会为防止高税率抑制富豪捐赠而引入扣除机制以来，此类税惠已普及至多数发达国家，包括美国的应税所得抵扣与英国加码25%的“礼品援助”（Gift Aid）机制。然而，这一补贴的财政杠杆效应正遭受严重质疑：圣母大学丹尼尔·亨格曼等学者在2024年的实证研究表明，政府通过税收减免将捐赠成本每降低10%，仅能激励捐赠额平均增加6%，这意味着国库损失的税收收入远超慈善机构实际获得的增量资金。

将税收减免视为由公民个人决定公共资金分配的“民主投票”理论存在重大缺陷。捐赠者往往依据个人狭隘偏好行事，导致道路维护、基础教育等缺乏光环的必需公共品被忽视，甚至出现纳税人资金变相资助极右翼团体“誓言守护者”或极端宗教场所的现象。更为关键的是，这种机制极度偏向超级富豪，赋予了极少数寡头掌控公共资源流向的特权；真正的慈善价值应当源于公民由内而外的纯粹善意，而非由公共财政对其进行低效且不公的税收补贴。

Tax incentives designed to encourage philanthropy frequently degenerate into tax-sheltering schemes and inefficient capital accumulation. The late property billionaire Sheldon Solow gifted valuable art to his foundation to capture tax deductions, yet his gallery opened for barely more than one afternoon a week; similarly, Elon Musk’s foundation amassed over $14bn in tax-deductible assets that largely sit idle, with its largest 2024 grant of $370m going to an affiliated charity serving just ten children. In 2020 American households earning above $500,000 claimed over half of all charitable income-tax deductions; by 2026, these forgone tax receipts are projected to cost the United States over $70bn annually, matching Alaska’s total GDP.

First introduced during the first world war to protect philanthropic giving from surging tax rates, such mechanisms now span wealthy nations, from direct taxable-income deductions in America to Britain's 25% Gift Aid matches. However, recent economic evidence debunks their fiscal efficiency: a 2024 study by Daniel Hungerman and co-authors found that a 10% reduction in the cost of giving via tax relief boosts donor contributions by an average of only 6%, proving that governments forfeit substantially more tax revenue than charities actually gain.

The argument that charitable deductions function as decentralized democratic voting for public-resource allocation collapses upon scrutiny. Individual donors consistently overlook unglamorous civic necessities like pothole repair and public schools in favor of niche pet projects, occasionally subsidising divisive causes such as far-right Oath Keepers affiliates or hardline religious groups. Ultimately, this framework confers disproportionate civic power to the ultra-wealthy, granting billionaires millions of de facto votes over public spending and underscoring the necessity to abolish charitable tax breaks in favor of self-funded altruism.
