Intellectual Property Reform. [View all]

I wasn't quite sure where to post this... but a thought occurred to me regarding intellectual property; Bambi.

Bambi was released in 1942, you know, during WW2. The original authors and animators are probably either near end of life or dead. Why is it that this film still cost $15? Why can't I share this work with friends or family?

Normally, works only last the author's lifetime. The constitution says intellectual property will be protected for a "limited" time. Why is the limited time more than a lifetime?

I'm pretty sure the reason is Disney fighting for more restrictive intellectual property rights and continuous expansion of these "rights". They've done so by buying politicians to do so. When will politicians say "enough is enough" and reform intellectual property?
