This is certainly hyperbole. Conglomerates are not the only ones with libraries. Many doctors are affiliated with universities which also have libraries.They could hire a student part time with the explicit intent of raiding the library. When I was a student I would do this. In most cases if a library does not have the article, ILL will get it.
In any case the example used in the submission is silly. The speech pathologists is complaining that the articles to do the job costs $1000. I make less than a speech pathologist and I easily spend $1000 a year making sure that I am up to date so that I can keep my job. It is like a few percent of my income. Expenses have to be put in context. If you are billing $100 a patient to medicare, and seeing 10-15 patients a day, it is out of line to expect some of that to be used for professional development?
That is not to say that journal costs are getting out of line. If some one is doing real science, and is trying to do so on a budget, journal costs can get out of line. Preprint federally funded research should be available online for little or not cost. Everything possible should be done to reduce the costs of professional journals to libraries. There are many things that can and should be done.
But an alleged professional whining that they get charged for a valuable product when they charge large amounts for their services, that is just silly.
A better example, and real problem, are those working in less developed countries in which the resources are actually taxed, and science, even medicine, is extremely strained because in some cases journal costs do actually provide a significant road block to possible innovation.In some cases journals are given free or at greatly reduced costs to those countries. Even so, the problems is not going to fixed until we have free rapid communications of peer reviewed articles.
