Probably it's not worth making this point, but I think that would almost certainly be a bigger, not smaller fraction of Americans, since I think Americans are more, not less, likely to read scientific research than the rest of the world.
If their expenses of 60-80% of revenue is "almost nothing", surely their revenue is also "almost nothing", and therefore we shouldn't care about it.

Besides, do you really think it takes 28,000 people to publish a single company's journals, given that the selection and review process is all being done for them on a pro-bono basis? There are massive efficiencies there - but the CEO of a 100-person non-profit couldn't justify a $30 million package, so there is absolutely no incentive for change.

The smaller American Physical Society made <$100,000 on $53.5m gross revenue in 2015:

So yes, it is possible to have high quality publications produced on much smaller margins. The question is whether it is possible to provide similar services for similar margins in a for-profit context. Given that for-profit companies, by definition, seek to extract the highest possible profits on what they do, one should really question whether it makes any sense for for-profit publishers to have the stranglehold they have on academic intellectual property.
I should probably have said "similar charges" as I said later. Reducing the margins to nothing can at best reduce the cost by 30% or so, which I doubt would satisfy most open access advocates; given that, the real concern has nothing to do with publishers' profit.
If anything, it's 1% of the world. The problem is not limited to the US.
And it's a very significant 1% which is one of the biggest - if not literally the biggest - drivers of the world economy.
>The counter argument to this is you pay to use national parks even though you already pay for it.
Parks have huge continuing expenses. They're also owned in trust for the public.
Journal publishing has almost no expenses at all. It's pure privatised oligoply. It provides no useful public or private service of any kind.
There is nothing academic publishers do that couldn't be done better in other ways.
