Right, sorry for the confusion. I was responding to two separate items in the question. One was the price, the other was the age of the article. I thought the question was clearly asking about both. Question 1: is $40 fair? Question 2: is that price (or potentially any price) fair for an article over 30 years old? My opinion is that $40 is not a fair price for a single article, and yet it's required to make the subscription business model work. And my second opinion is that the duration of copyright should be shorter. Obviously these opinions are in conflict with the business with which I'm involved, and are certainly not shared by most others within the industry.
