There was a belief in "the end of history": that any economy that developed would inevitably become a liberal free market democracy.
I think this has left its mark. A lot of people do not seem to be able understand that this is not true. Even if they accept it intellectually its such a fundamental assumption that its still influential.
I think there was, and is, an element of racism. It still persists in that a lot of westerners cannot comprehend that they can be overtaken technologically or threatened by non-western societies. This includes people who think they are not racist, or are anti-racist.
