Copyright being as long as it is is a theft of our culture. I (and many of our generation) grew up with Pokemon, it's a common experience for many of us. A classic of our culture. Except we're not allowed to use it, remix it, build our own versions, etc. We still do, of course, but it's all illegal.

It didn't used to be this way.

I think 20-30 years of copyright should be plenty to extract whatever profits you deserve from the fruits of your labor. Anything beyond that is just holding culture hostage for the benefit of a few. It doesn't serve society in any meaningful way.
