Social proof — how other people, especially other women, visibly respond to and treat a man — functions as one of the most important status metrics inside Status as Relative Standing (The Real Attractor Behind LMS). It lets an observer infer, without direct evidence, that a man is "pre-approved," popular, and competent/provider-capable.
Looks and money mostly create attraction indirectly, by generating the kind of visible social proof and status symbols other people react to — rather than attracting on their own. Money converts into status through two channels: buying visible status symbols (e.g. a flashy car), and buying access — entry into high-status venues or proximity to high-status people — which grants vicarious status, a borrowed form of standing and influence gained through association rather than direct demonstration.
See Absolute Value vs. Relative Value for why a status symbol or access purchase only pays off in attraction terms when it's perceivable within the interaction, and High Value by Accident (Effortless Competence Narrative) for why direct disclosure of wealth undercuts the same signal.
