Most journal reviewers and editors are academics who do the work as public service, i.e. free. Even top spots like editor in chief only get an honorarium of maybe 10k a year. Considering these people are the top of their field and can easily command 6-7 figures salary at minimum, that amount is nothing. Only very few journals have full time editors and even those end up relying on the volunteers to vet and review articles.
A full time professor is expected to be an editor for some journals. And these academics make up the bulk of "journal editors". But they would not list it as their jobs. I suspect that is why if you look for "editor jobs" you will get lobsided salary ranges that doesn't reflect reality.
