I think his point is you wouldn't get the same thing. If Winnie the Pooh entered the public domain today, a decade or two from now nobody would know who he was. You might get some cheap Pooh-themed lunchboxes from China early on, but without Disney pumping money into him, Winnie would fade into obscurity. (e.g. Винни-Пух, the people's Winnie)

As for the wealth they create: http://americasmarkets.usatoday.com/2015/06/24/disney-gets-1...

That's actual college-and-braces money that shareholders are making on the copyright, that otherwise wouldn't exist. And don't say that money is being stolen from us, because first of all, we're all potentially "them", and second, we all get to watch Winnie's Big Adventure on Netflix.
