I suspect you're thinking of big creators with those numbers, which is understandable, but copyright isn't only about "protecting" Disney and major record labels. Indie authors, musicians, comic creators, and so on are out there, too, and building up a "library" of works for sale is virtually the only way indies are going to be able to make the bulk of their living wage from their works. Five years just seems too short in light of that. Personally, I think the original US Copyright Act of 1790 -- based on an even earlier British statute -- had a pretty good approach: a 14-year term granted upon publication, renewable for a second (but only a second) 14-year term by a living author.
