It is hard to see how the world will get by without a major global rethinking of taxation-and sooner rather than later. Tax issues are sufficiently complaex that any idea for changing taxation comes with strong pros and cons. But one thing is sure: the changes that will inevitably have to be made in the methods of taxation should happen in some countries but not in others, if we are to avoid an unholy and unhealthy mess. The world would be far better off with some sort of global framework for rethinking taxation for the twenty-first century. 

It would be best if this rethinking started very soon: the cat is already out of the bag, and the traditional, most territorial taxation approaches perfected in the twentieth century are poorly adapted to what is to come.
