there are more factors than only "girls mind if their BF's are
poor".
let's assume a girl is not materialistic by nature.
But does her parents mind?Maybe her parents are materialistic, they
hope their future son-in-law is a rich one.
Let's say her family dont mind. People around her, like her frens,
perhaps are those materialistic one, they will tell her how rich
their bf are. The girl start to compare, and eventually also want a
richer bf.
