I think you have to consider things in the wild. Of two men, which one is going to survive better with limited resources like food and water and the threat of predators? Which one is more likely to be willing to eat his neighbors if it came to that? Yeah, someone who earns more money is better off and has the provider status, but that may not necessarily be who a woman wants to be with or have a sexual relationship with. If a man is successful financially and is someone who would be willing to eat his neighbors if it came to that and his familiy starving, then you have a complete package right there
