I think you need to rework some definitions or vocabulary if "overwork" is solved by "raise".

Maybe in extreme cases where a raise translates into big time savers like a maid, but those are not the type of raises you while keeping the same job.

For tech folks that are making comfortable salaries, a raise won’t help.

But if you’re in a position where there is difficulty affording your living expenses, a raise can make a huge quality of life change. It can remove enough stress from your life that the stress of your job goes from pushing you over the edge to staying within your limits
