Earlier quoted context omitted.
The people who conduct the research, and the people who fund the research, are not collecting the fees to view the research.
The open access journals charge thousands. Journal publishing has costs, and they need to be born by someone. If not from access fees, they'll need to be paid upfront, which means each study costs more, which means either less studying gets done, or funds come from elsewhere to fund it.
I've yet to see any justification at all for the outrageous fees charged by academic journals.
The only costs I can see are printing/distribution and web hosting.
Typesetting is trivial. Editing is non-existent. Editorial isn't paid. Peer review isn't paid.
Having a nice office and marketing staff who hold university libraries to ransom shouldn't count as a cost.
