I am generally in favor of reduced copyright terms, as a consumer of these works, but the thought has crossed my mind, that authors may be motivated, to some extent, by the idea that they are leaving a long-term financial legacy. I come from an extended family that once had substantial commercial real-estate holdings, mostly bought by my great-grandfather, and my grandfather and his brothers, with the explicit intention that these properties would help to support multiple generations of descendents . Most of them were lost, but even now, I derive a small income from a share in one of the properties, that I am grateful for, since I apply it for the benefit of my own children. Although the real-estate/IP analogy does break down at some point, should authors of works not have the right to ensure that their works benefit their granchildren, and great-grandchildren? Does this help to motivate at least some of them? These are not rhetorical questions, and it would be interesting to see what the answer is.
