First, the situation is more complicated outside of math/physics/cs. E.g. in biology, getting papers is much more complicated, which has connections to computer literacy of authors, conventions in the field, and maybe also conditions of the journals.
Second, if you are an institutional researcher, there are good chances that your institution has subscription to the major places relevant for your research.
I hope it's a problem solved over time largely by natural selection. I'm much less likely to cite papers that I can't read easily.
AFAIK Elsevier's pricing structure and conditions on things like arxiv uploads is much stricter than Springer's. Not sure though.
