I don't know about "only the rich" but certainly in my country, from the 80s onward (when I began to be aware of prices) books were never anywhere near as cheap as the prices cited above. Even back then, the equivalent of $5US for any book of any sort would have been so low as to cause amazement. My family was lower-middle socio-economically, but despite being a family of voracious readers, we owned few books, relying heavily on libraries. Most of the books we did own were sets brought out when my father's family immigrated/emigrated - which does at least show how much they valued books.
