The US government pays at least $50,000 in grant money for each paper, but it can't find $5 to make it available for the public in perpetuity, as does the arXiv.org preprint server.
(arXiv.org looks, on the surface, to be a success, but always been functioning on operating budgets that are meant for something else... It's existence has hung on a thread more than once It still struggles to find a sustainable funding model, despite the fact that it costs 1/200-1/1000 as much to make papers available on arXiv.org as does a peer reviewed paper)
Frankly it seems to be an insult to the taxpayer that we pay for research and can't read it/
