I have never, ever, ever brought India and China into the discussion of the other.
Both are very different countries, born under very different circumstances, and having a very different historical narrative. Also the relative success or failure of one, doesn't stop me from talking about anyone of them.
According to me, in general both of the countries have been successful, with China leading here. I even doubt the singular aspect of being successful in general, because the success and failures are also divergent. India has been successful in some areas, while China has been more successful in some other areas.
As for language. To be honest, it is very imprecise to say that someone has left behind his language. Due to the conditions of India, we had to adopt English as a unifying medium. Even you people did abolish all the local languages and dialects spoken. Everyone was told to speak putonghua, taking away the beauty of the diversity of Sino languages and dialects. Be it Cantonese, Shanghainese. etc.
But, yes overall, disregarding the relative minute peculiarities, we have generally adopted English much better than Chinese have. You seem to think that is a bad thing. I am not really sure. English is indeed the defacto language of the world.
This whole dichotomy of values, be it labelled "Western" or "Chinese" or "Indian" is extremely ideological.
Their are values. While, yes arguably some values can be different among cultures, they are much more affected by socio-economic conditions. Also, any value isn't limited to any group. Rather, all sorts of values are possessed by all groups, and yet people can form a slightly different value set, by forming their own unique permutation of those values.
