Would you support a government-run cultural fund which buys all rights to work from the author at market value for taxpayer money and move it into public domain? E.g. the billboard top song for 2014 was by "Pharrel Williams". Should we pay this Williams e.g. $500,000 so this particular song cannot be locked up by whoever owns the copyright and can possibly hidden away like Disney did with some movies, but returns to those people who enjoyed it in 2014? Alternatively, this fund could be run by a private entity. What would you pay to outright buy irrevocable permissions world-wide for e.g. "The Capital in 21st Century" which sold 1.5 million copies? It seems like you cannot measure the impact of a book until after it has become a bestseller, so negotiations may be problematic, as the more popular books will end up being expensive. The "copyright foundation" could I guess, keep selling the books but would need to pay for their future value to the current copyright owner.
