Until you’re over the many hundreds of thousands of dollars per year range, it works pretty well as a rule of thumb. If your company wants the cost of working in an office, they’re probably not paying high salaries to work in a rundown shack and the people making those high incomes also want better quality benefits (especially in the United States where healthcare is so expensive and cheaper plans mean more time having to argue with someone whose bonus is based on denying care).
Does that scale neatly with salary? I would expect it not to, with things like benefits and other costs being relatively fixed regardless of salary

I assume people who are paid more also typically receive better benefits
