In Season 6 one of the main storylines is a summit in China. In the episode A Change is Gonna Come Kate Harper and Will Bailey are sitting with the Chinese delegates going over the agenda when the Chinese officials receive a call from within the White House.
Will Bailey makes the comment "I thought cell phones weren't supposed to work in here." To which Kate replies "They aren't."
Two episodes later (in Impact Winter) the president is incapacitated and needs the chair lift to leave Air Force One. Kate is speaking Chinese to the official when the following dialogue is exchanged:
Toby Ziegler "Pretty snazzy with the language there."
Kate "Not really, just a second grade level."
Toby "Hydraulic compressor lift is second grade?"
Kate "Around here it is."
That is at least twice that the series is trying to say that the Chinese are superior to the United States from both an educational and technological point of view. Why?
