A lot of garish displays of gold due to Indian culture and other more internationally modern signs of wealth for the first and some of the second generation. As with every culture, eventually the third and fourth generations will settle on a more restrained persona that downplays their actual wealth, especially to outsiders. For example, thing that people from poor and middle class backgrounds, even if they become moderately wealthy can miss is that scions of wealthy families don't usually engage in conspicuous consumption as much. Branded clothing and garish jewelry is one of the stronger indications that someone isn't from generational wealth.
At the same time a person can still tell if a westerner, Japanese, Korean etc is from a well off family a lot of times from their clothes due to the cut and the quality of the clothes. Company logos, if the clothes are not custom made, that are visible to others are more seen as undesirable unless the wearer is an owner of the brand or for some other specific reason. A lot of wealthy Chinese are still in the first and second generational peacocking stage, and I wish to remain diplomatic so I'll simply say that people I know from established generational wealth do notice things like that.
It's their economic policy to export themselves out of poverty.
Its a good thing for foreign countries if they have the understanding that they are better off accepting high performing migrants from India and other places in the world for that matter. Look at how a lot of talented Indian medical students study to take the US equivalency exams after their Indian schooling finishes. Having more talented and motivated physicians is a net benefit to any society. But consideration must also be made to immigration policies as large amounts of lower quality immigrants can cause issues if they become too much for the social, economic, and cultural nets of foreign countries.
