I have worked with people who have as many years of experience as me but are at a very different seniority level, for example by learning less (or more) in their prior jobs than I did.
If you were to hire them and me for a role where that difference is relevant (as it often is), we shouldn't be in the same seniority of job and shouldn't receive the same salary.
