I argue, because of the views I've developed, that governments typically face spending problems, because there are always more demands than you can possibly meet. There are going to be hundreds of groups coming before you at this committee saying, “Spend, spend, spend, or the the world's going to come to an end. The end is nigh.”
My joke about professors and MPs is that you have to learn the most difficult word in the English language, which is the shortest word in the English language: “No, I am not changing your grade”, or “No, I am not giving you the money, because it's not justified”.
