primarily wants to enjoy the wealth of their date or partner

just wants access to their bank account

The words "primarily" and "just" here seem to me unwarranted. Things can be important without being the only important thing.

I also think you're displaying little imagination about the usefulness of salary as information. For example, OKC has many questions about (and another sidebar slot for) persons' interests in/preexisting status regarding children. There are questions about marriage, etc. - lifestyle stuff. Salary is a factor in what kinds of lifestyles are available! Somebody who is trying the radical experiment of life off the grid by attempting to live off barter and urban farming without the use of filthy money isn't for me, any more than someone who abhors the institution of marriage and never wants children would be for me. Those lifestyles are not compatible with what I want.

Or to be yet more specific: Currently, I live with roommates who don't expect me to pay rent because I cook tasty food and do some cleaning. This is sort of like being a house spouse without the "spouse" part, and you know what? I like it as much as I thought I would! It suits me very well! I'd like to go on with this sort of lifestyle, barring the insistent knock of implausible opportunity, even after I settle into a long-term relationship. But the thing is - this arrangement only works with someone else funding the operation. People who cannot fund that operation (which funding doesn't take pockets with extradimensional space in them, just a steady and livable income) are not offering a lifestyle that is maximally appealing to me. That's a factor, even an important factor, without being a matter of me just wanting to dive into a potential match's wallet.
