请指教关于 than（宾语比较）的一个例句

irisdelis

The man was always
aware, sometimes proudly and sometimes resentfully, that he was a
small-town Midwesterner thrust into a world dominated by wealthier,
better-educated, and more polished people than he.

为什么用he而不是him呢？ 这里比较的应该是介词by后面的宾语...

不理解，请指教，谢谢

irisdelis

有没有nn指导下阿?谢谢
