America is so materialistic and primitive?

I watch 90 day fiancé. It’s a tv show that American boy or girl invite foreigner to America to get married in 90 days. It’s the same thing I see that they get together with family and their family start talking about money from the first meeting, I don’t understand. In my culture, money is privacy. They don’t talk about money at dinner table like they do. It’s so fucked up. And I thought that matriarchy exist in underdeveloped country but obviously America is inclined to matriarchy in so many American family. Americans are that primitive?
