I can’t speak to this, but I can say that many of the Japanese-born students I taught expressed many of these same concerns to me. My female students felt discouraged that they would not be as successful as their male peers after graduating university. Many of my brighter students lamented the job culture and the lack of startup chances.
There's probably selection bias in your experience. They may have come here for school because they were among those that disliked their native culture the most. They may have picked up American values and priorities after arrival etc.
> There's probably selection bias in your experience.
Is there any argument at all that would convince you? A foreigner is unconvincing because he/she is a foreigner, and locals are unconvincing because of selection bias. So what would convince you?
