This is kind of you, Mama, but as you can see, I'm miles better.

多谢你，妈妈。您也看到了，我好多了。

Even with all their problems, pensioners that depend on underfunded public DB plans are miles better off than those relying on Social Security (the American equivalent of National Insurance).

即使存在所有问题，依赖资金不足的公共 DB 计划的养老金领取者也比依赖社会保障（相当于美国国民保险）的养老金领取者好得多。
