I mean, this is really one of those things that people just soooooo overthink. So totally overthink.
Here's the rule, y'all:
RESENTMENT = DOING IT WRONG
NO RESENTMENT = DOING IT RIGHT
Really... That's it. That's it. Whole enchilada. End of. Period.
People just have such different styles, when it comes to this.
On one end, you have girls like me. I... just don't like spending other people's money. That even extends to joint money that other people earned. I mean, I like to buy frivolous shit from time to time, but that's mostly because I'm the main earner in the family. If our incomes were flipped and my man out-earned me in a 77/23 ratio, I'd just feel guilty as hell spending the money HE brought in on the same frivolous shit (even if it's for him!). Even if it was totally ok with him. Not rational.
On the other end, well, you have gold diggers. And you have girls who, while not actually gold diggers, are more "old-fashioned" about this. (Yes, people, there are non-gold-diggers who still have that sort of values system.)
Similarly, on one end you have men who just like to throw money around because it makes THEM feel good to throw money around. Same men who like to "entertain" and who regularly buy rounds for everyone at the bar. These are the kinds of men who'd almost be offended if you didn't LET them pay for you.
On the other end you have literal gigolos and pimps, and other assorted men of that stripe. And the scorecard-keepers and all that shit.
There's just such a huge variety that it's pointless to try to generalize, and it's arrogant to think that others should approach the issue in the same way you do.
I think it's only common sense that, when two people earn VASTLY different amounts of money, the higher earner should be paying more, in general. Because, well, duh. And also because it just isn't gna be logistically possible for those two people to go out together, otherwise. (The higher earner won't be content spending 100% of the time doing things that the lower earner can afford half of. If he/she were content with that, he/she wouldn't have put in the effort to become the higher earner in the first place! LOL)
Beyond that, no harm no foul.
