Overall government revenue worldwide is maximised by balanced copyright - that promotes the more efficient creation of taxable creative works, and use of copyrighted works in business, by allowing reuse of public domain works, but still incentivises forward progress to further enlarge the pie of which the government gets a slice. I suspect that at the moment, balance means shortening copyright terms drastically. Overall campaign finance revenues, however, are maximised by supporting copyright expansion, because copyright holders who already own substantial collections of copyrighted works are willing to back politicians who support their interests, but there is no equally big pot of money for politicians in favour of balancing copyright. It is one of those cases where what is essentially legally sanctioned corruption allows for regulatory capture of the political process against the interests of the government and public.
