This is closer to the mark, but I still assert that the sacrifice is not a positive contributor to the appeal.
It’s not the sacrifice, it’s the willingness to sacrifice, that thereby demonstrates commitment—that one is capable of protecting and providing for one’s partners.
This is a distinct and separate measure from the amount of resources one has control or influence over. If you have a lot of resources, but are stingy, then you might actually be less suitable than if you had few resources but were willing to risk them all on something you believe in… as long as your potential mate believes they can get you to believe in them.
