Most men love money and security more, and creation and construction less, as they get older. - John Maynard Keynes

The ideas of economists and political philosophers, both when they are right and when they are wrong are more powerful than is commonly understood. Indeed, the world is ruled by little else. Practical men, who believe themselves to be quite exempt from any intellectual influences, are usually slaves of some defunct economist. Madman in authority, who hear voices in the air, are distilling their frenzy from some academic scribbler a few years back. I am sure that the power of vested interests is vastly exaggerated compared with the gradual encroachment of ideas.

I find economics increasingly satisfactory, and I think I am rather good at it. I want to manage a railroad or organise a Trust or at least swindle the investing public
