Nevertheless, according to Brigitte Madrian of Harvard University, automatic enrollment in savings plans is critically important, even if the employee is completely free to drop out. If employers tell their new employees that a pension saving plan is available, and even promise to match employees’ contributions, a significant fraction of employees still will not participate.
但是，哈佛大学教授马德琳认为，即使雇员完全可以自由退出，自动参加储蓄计划也是极为重要的。如果雇主告诉他们的雇员说现在有一项养老金储蓄计划，甚至保证也交纳和雇员同样多的钱，很大一部分雇员依旧不会参加。
