What we've seen in the U.S., and some of the more Western, industrialized countries over the last 25 years, is the removal of entry-level jobs and the removal of the simple, repetitive manufacturing jobs.

the U.S. 和 some of the more Western, industrialized countries 是并列成分，作介词in 的宾语。

形容词Western 有比较级和最高级形式，more Western 意为更加“西方化的”。

其实，这个说法并不矛盾。美国虽然发达，但也仅有几百年的历史，比起欧洲一些历史悠久的发达国家来说，只是发展较快而已。

They would follow their own trajectory and not become more Western. 他们将按照自己的轨迹前进，但不会变得更加西方化。
