But the thing is, almost all of the work is already done by volunteers! Reviewers and even most editors for journals are academics giving their time for free. Basically the one thing journals due these days is typeset. As weird as it may sound for those in math and physics, most of the scientific world doesn't use TeX/LaTeX. Instead, they submit a manuscript in Microsoft Word that needs to be typeset.
