If somebody dumped a million dollars in a pile in your bedroom, would that fact alone make you more desirable to women?

Of course not. What would make you theoretically more desirable: You might stop caring so much about individual women once you're well off. You might have more free time to socialize. You might dress nicer. You might cook more or get yourself a nicer place.

That's what makes you more desirable. That's all achievable without the money. You don't need to be rich, you just think you do.
