Some salaries are in really expensive cities. Some are fake salaries. Some people have landed great salaries by a combination of luck, being at the right place at the right time, plus good networking. Some people fake their way into high paying jobs (as in: managing to pass the interview stage without actually having the skills) and then work their asses off to cover ground.
On the other end, maybe you are not fit enough for such jobs and one would need much more info to give you helpfull feedback. Eg, send a job listing you would like to land and analyze were you lack.
But whatever the answer (other people may help in this comment section) never but never think that what a person is paid is 100% reflective of their value or the value they provide to a company. Many are paid less than what they are worth, many are paid more.
