Even if you don't have an affiliation (or your school doesn't subscribe to a particular journal), if you use Google Scholar to search for an article you can easily find pre-prints which are essentially the same thing. Additionally, if that still fails then the next option is to just email the author - they actually want you to read their work and will just send it out.
The real issue is that the societies are essentially extorting universities for hundreds of thousands of dollars per year when the writers have to pay to submit and readers have to pay to read. Many of the newer journals are becoming open access, but few of them have been able to make enough in roads to be considered "good journals." This is a completely separate topic than the one from the above article.
