The ratio of interracial marriages between south asians and local Americans is not very high. But even then, people can find a little bit of emergence of different systems of cultures in the USA.
INDIVIDUALIST CULTURE: In these systems/cultures, competition is more encouraged than cooperation. These systems are mostly "I oriented". Some examples of countries having these cultural systems are USA, Australia, UK, Newzealand, Italy and France etc.
COLLECTIVIST CULTURE: In these kinds of cultural systems, cooperation within valued groups is emphasized and these are "we oriented" systems. India, Nepal, Pakistan and Bangladesh etc are some examples. It is important to know that no culture is completely individualist or collectivist. But intensity varies.
