Thanks to youtube, we are satisfied enough. These people are asking for $50 for the article. Weird.
I think the fair value of what Elsevier (say) provide is > $0, but it's interesting to compare with say Spotify or Netflix - who actually have to pay for content.
Speculating: the reason they slap a $50 charge "per paper" for non affiliated access is that they don't actually care about those sales, that's not where their revenue comes from. Essentially that is the "sucker price".
At this point, other than being the arbiters of prestige, what do the journals offer that direct peer review does not?
