In practice so far, it hasn't fared any better, but probably not worse either.
Like in the U.S., one of the biggest hindrances or obstacles to success is segregation (forced or by choice). Wanting success essentially entails assuming the culture and practices of the successful, but for some fraction of people, being malleable and becoming like the mainstream is antithetical as it's interpreted as "giving in" to the larger culture, while simultaneously wanting to be part of the larger culture and to be accepted by the larger culture. So there is that ambivalence.
Personally, if I wanted to succeed in China or Mexico, I'm willing to bet I'd improve my chances by adopting local customs, manners and attitudes, rather than being steadfast about my own. [it's somewhat peculiar some Americans are sheepish about being "too American" while abroad but simultaneously believe that integration into the mainstream isn't all that necessary. It tells me that their brain tells them one thing, but in practice, when given the opportunity, try to be like Romans while in Rome]
Personally, I think people put too much stock in group identity over say, personal identity. But you know, let people do as they wish.
