Wdym? Scientists usually don’t get paid to publish. The person you replied to, probably meant academic publishing as in:

1. Scientist does research and compiles manuscript, usually via public money, even in shithole countries like the US
2. Scientist submits manuscript to for profit journal
3. Journal outsources proofreading to other scientists, who do it for free
4. Manuscript is accepted or revised on scientists time and money
5. Scientist pays for publishing
6. For Profit journal either charges extra for “open” publication or charges scientist and other scientists for access, usually by agreements with the respective library
7. Profit! (On the journals part)

Where is the split of compensation? For patents there is, but for academic publishing usually not.
