Lemme try to break it down:
Generally speaking,
⬆️ Corporate ladder = ⬆️ Income

Girl POV:
See man ⬆️ Income = ⬆️ Attraction
Replace the equation...
See man ⬆️ corporate ladder = ⬆️ attraction

Man POV:
See woman ⬆️ Income ≠ ⬆️ Attraction
You get the rest...

I think you may not see the connection, perhaps because you think women climbing corporate ladder is not necessarily associated with money, but perhaps just a sense of achievement in general. In that case, you're right it's unfair, but society often works in collective thinking / stereotypes so there tends to be a skewed perception between men vs women in this context.

I'm saying unfair for her because she's not in the stereotypical group, that is to say, your generic statement of wo/men's benefits also will not apply to her.

That said, I'd be careful to apply statistics to everything. In this context, TS isn't talking about a(ny) rich guy, and as a career woman, also less so in the women stereotype.

Anyhow, I think any couple who are happy together will always have some transactions between them, because happy couples are partners contributing together to the relationship, because no one would be happy to be 100% giving and 0% taking for a lifetime. I'd go as far as to say, a successful gold digger has her ways of making the rich man happy, which also means the benefits he gets is happiness.
