I don't think it's strictly an Asian thing. A lot of first generation Americans have this expectation. It's very common to see their parents remunerate money back their parents in foreign countries.
It isn't. This is typical of most 1st gen immigrants. Growing up in NYC I have friends who were Sri Lankan, Polish, Italian, and Guyanese who's parents came here and worked their asses off to provide a better future for their kids while sending money back home.
