If there's a single fixed number (rather than a range), there's probably a reason for that (might be a government, university, or institute role with a fixed pay schedule, for example) and as a hiring manager, I'm assuming you're applying for the job as published, including the comp number.

Let's assume the amount is fixed. One approach is to ask to re-frame the position to be better value.

Ask for working hours that effectively pays you more per day, like an 80% contract at the same comp. If they mumble HR and hours, offer to do 4x10 hour days. The magic phrase in corporate is "flexible working". This doesn't solve your comp going up, but you get a 3-day weekend and 52 more holidays a year.

This one even works at intensely bureaucratic organisations like universities. With grants, the amount you can be paid is very fixed, but almost anything else can be approved if three people sign off on it.

Did you read the post? The numbers are fake, is how. That's the whole point of this post. They're arbitrary, made up, totally subject to change. The idea that they're immutable is corpo-propaganda designed to worsen your performance in a subtly adversarial encounter where it benefits the company for you to think you have no leverage. Job offers use craigslist pricing. They don't describe the actual desired end state. They put down an anchor in a favorable direction with the expectation that it will get haggled on for a round or two.
