Certainly people do not seem less interested in success and its signs now than formerly.

【翻译】无疑，人们现在对成功及其标志的兴趣似乎不亚于从前。（其标志=成功的标志）

【分析】这是一个含有比较结构的复合句。

主干部分是：less interested (more interested的反义) now than formerly（真正比较的核心词是now 和formerly）

1. seem 是系动词；less interested in success and its signs 是表语。

2. than formerly 是承前省略了they did 或they seemed。
