It seems as if there are only two possible ways out of this mess. In the good but less likely scenario, the proponents of reform succeed, through a heroic effort of leadership, in persuading not only the young but also a significant proportion of their parents and grandparents to vote for a more responsible fiscal policy. As I have already explained, this is very hard to do. But I believe there is a way of making such leadership more likely to succeed, and that is to alter the way in which governments account for their finances.
