I just watched the tape of the dream crushing episode. I think CCL is right on on why it is difficult for this to translate to the US. Another variable in this version tho is that I think Roy realizes that if she does this he will lose her--she won't be "just" a receptionist anymore, and his social equal, she'll have started moving up, as one can more easily in the US. So what's in it for him to encourage her?
I've heard a lot of similar stories re women who go back to college when their spouse/friends don't. Friends who drop you when you start using "big" words, a wife who had to hide her typewriter in the oven (the one place her husband would never look ) so that her husband wouldn't break it to prevent her from finishing papers on time (she got her BA and left him, big surprise). Not that all friends/husbands are like that, but it does happen.
