Leaving husband if he loses his job / earnings

Male 27, I've been talking to a girl for over two months, and we recently discussed marriage and finances. She mentioned she wouldn’t stay with her future husband if he lost his job. This seems to be part of a pattern—she often demeans men she sees as "below her level" and talks about wanting a lavish lifestyle.

I’m wondering if this is a red flag. What’s interesting is that she says she’s looking for love but approaches relationships in a very materialistic way. What would you do in my situation? Is this normal or should I run for my life?
