What basic society skills most people lack?

Living in u.s, and I'm always getting lectured oh you have to live in Indian culture. Marry someone from our cast and don't do things that will disgrace our name and always aim for higher and better in life. I kinda don't like living in this sorta narrow minded mentality. Like whenever I attend wedding function or family gatherings, people act so fake especially with the greeting and always comparing about how you dress and mainly topics are oh when you will get married. Did you find a high paying job. Are you done with college. Like c'mon what is all this. Asking questions about my personal life.
