As I wrote in my Globe column for the ROB, carbon taxes are all the rage, but they are not going to be the tax reform that will bring national tax systems into the 21st century. Governments and their traditional tax systems have become the latest bystanders sideswiped by the globalisation juggernaut, and the shift from corporate taxes to more objective tax bases like sales and consumption are going to be the response. In this context, people should stop ventilating and look more closely at the Republicans’ border adjustment tax. In my estimation it is a back-door way of introducing something like a much needed national sales tax in the US.
