Here's how academic publishing works.
- You write the paper. Your peers review it for free. The journal charges people to read the paper to cover copy-editing/hosting costs, and to make a profit.
- You write a paper. Your peers review it for free. The journal charges you to cover copy-editing/hosting costs, and to make a profit, then gives it away for free.
Unfortunately you're not allowed to save money by doing the copy-editing yourself, nor are you allowed to use your institution's infrastructure for hosting. You can't submit to a university-run committee to organise the peer review.
To be taken seriously you have to publish in the well-known and established journals of your field. To publish in those journals you (or the tax-payer or funder) have to contribute to the publisher's profits.
To answer your question more directly, they won't be giving any of those profits to you.
Edit: forgot to say, for anyone who can't afford to pay for scientific articles (or who wants to make a point), you can access the majority via Sci-Hub.
