I am an author who relies on copyright for part of my living, yet I agree that copyright protection lasts too long. I feel like it should protect the work for a reasonable time--say 20 years--after which one must pay an initially modest but exponentially increasing fee to renew the copyright every X years. Big players like Disney could afford to keep their stuff out of the public domain for a while, but not forever. And many deceased artists' work would slip into the public domain when their estate could no longer afford the renewal fee.
