Earlier quoted context omitted.
There's one point you're missing, and that's that you're only talking about people in America or other rich, large countries. The money is an incredible bar to, say, Hungary.
What? I'm not talking about that at all. I'm saying that most papers are already available to everybody who wants them, whether they're from the US, Hungary or Botswana (as long as they have an internet connection and basic research skills).
No. No, they're not. Unless the field in question has open archives like arxiv.org, and medicine (to take one at not-so-random) does not - or at least didn't until the NIH started doing the right thing. This has always been perceived - rightly or wrongly, but I suspect there's a lot to it - as one more way America oppresses the little guy. Or in this case, the little country.
