前輩好，有一段原文想請教：
that後面那句
｛that are increasingly out of geographical sight and mind.｝
是在補充說明［the lower classes］(下層階級)
還是在補充說明［real duties］？
the ruling class’s insistent defense of equality is a way of freeing
themselves from any real duties to the lower classes that are increasingly
out of geographical sight and mind.
試譯
統治階級的堅持捍衛平等，是一種讓自己擺脫對下層階級負有任何實際責任的方法
而這樣的責任越來越超越地域視野和想像。
還請指教，謝謝
