下面是蔡的一段原文： 

Taiwan’s social safety net is on the brink of bankruptcy. My pension 
reform aims to make it sustainable and increase the support for the 
poorest. Taiwan has different pension programmes for different 
professions: an unfair practice which fuels social divisions. Changing 
this system will take some effort, but the DPP has a clear democratic 
mandate to do so.


其中的social safety应该是social security.从后面的原文跟进，应该是指social security。另外，我们通常讲social security system,而非
social safety net，即社会保障体系，而非社会保障网。

如果不是我的理解是错的，那一定台湾的英文有问题，否则就是蔡英文的英文太菜鸟了。
