Also, copyright isn't about compensating authors, but publishers. Authors are basically an afterthought.
In regards to countries with weaker copyright enforcement, I think there's a bit of an inversion. Most countries that fail to properly enforce copyright do so due to a lot of structural issues, which also hamper creative thinking for independent reasons. China would be an example of a country with weaker copyright enforcement but also with good infrastructure, and it seems to be overtaking (if it already didn't) the US in terms of creative production (both for copyright and patents).
