The following plan restores Social Security to long-range actuarial balance by providing additional funding while making that funding somewhat progressive, as the benefit structure already is. It also is a response to the upward redistribution of income and wealth over the last few decades, which is projected to continue. The progressivity of the funding mechanism would result from a universal $20,000 exemption applied to first-dollar earnings, coupled with application of a principle that already has been applied to Medicare funding: taxing the full amount of wages with no cap. Thus, the higher the wages, the closer one would be to paying the current level of 6.2 percent, although no one would actually pay quite that much. This would not undermine the principle of earned benefits, since very few beneficiaries would have average wages below $20,000, and even for those, there still would be a requirement of the requisite number of credits in covered employment.

面向未来的社会保障：一项扩大福利并增加系统资金渐进性的财政建议（以及缩小覆盖差距的其他建议）

以下计划通过提供额外资金，同时使该资金有所进步，使社会保障恢复到长期精算平衡，因为福利结构已经如此。这也是对过去几十年收入和财富的向上再分配的回应，预计这种再分配将持续下去。资助机制的渐进性将源于适用于第一美元收入的 20,000 美元普遍豁免，再加上已应用于医疗保险资助的一项原则：对全额工资征税，没有上限。因此，工资越高，人们就越接近支付当前 6.2% 的水平，尽管实际上没有人会支付那么多。这不会破坏赚取福利的原则，因为很少有受益人的平均工资低于 20,000 美元，
