Meanwhile, thousands of works that are not commercially valuable will be locked up by this copyright extension--so many movies and songs and books that weren't in print, that aren't selling copies, could have entered the public domain, but now it will be illegal to copy them. Harper, you are such an asshole.
Copyright in the early 1800s (in Canada, the U.S. and Britain) lasted 14 years with an optional extension to 28 years. We're not talking "life of the author plus 14", we're talking "14 years in total". Since then, every increase to copyright term lengths has been retroactive, demonstrating that lengthy copyright terms are not designed to encourage authors and artists to create new works, but merely to make even more money for the most successful works, to pad the pockets of the rich with payments from the poor, to limit the ability of authors to "remix" old and obscure works from the past, and to limit the public's ability to enjoy older works freely.
It's interesting to wonder what the world would be like if we still had 28-year copyrights. Every hard drive would probably be shipped with a library of thousands of older books and songs (Why not? It would only require 1-10% of the disk space on a 1TB drive); YouTube would let you watch any movie or hear any song made before 1987, for free; Google would search all older books and screenplays whenever you search the internet; filmmakers could create new films on a lower budget because they would be allowed to put any song published before 1987 in the soundtrack, and they could re-use art from older sources too; anyone would be allowed to write translations of older foreign-language works; bloggers could link directly to any paragraph of any old book (because the full text of all old books & movies would be on the internet) and low-budget academic researchers could do large-scale analysis of, let's say, every book written between 1885 and 1985 (or whatever).
Such a world cannot be observed, though, since wealthy interests have made sure that every country in the world adopts a minimum copyright term of "life of the author plus 50 years". This is called the Berne Convention, and almost every country in the world has been forced to adopt it, which means we will probably never find out what life would be like under a 28-year copyright term. Since 1887, powerful organizations like the WTO have forced all poor countries to adopt not only the Berne Convention, but other onerous "Intellectual Property" treaties, notably TRIPS. Now, the U.S. and many other countries are negotiating The Trans-Pacific Partnership (TPP), a new so-called trade agreement whose text is a secret. The TPP is rumored to contain even more corporate power givaways in the name of intellectual property, and a lot of other garbage that has led to all kinds of opposition across the political spectrum:
Pretty much every identifiable progressive-aligned organization is against it, including human rights groups, environmental groups, faith groups, legal scholars, consumer groups, food-safety groups, LGBT groups and many, many others. ... Polls show that the public is overwhelmingly against it. (Even conservatives are opposed.)
