"Money as such is, as Oscar Wilde said, perfectly useless. You can't eat it, drink it, shelter yourself from the cold with it, wear it, or make love with it unless deeply disturbed. In and of itself, it has no emotions, no mind, and no conscience. It doesn't put out flowers or have children, and it makes a lousy pet. It has meaning only when it circulates, and is exchanged for other things; and money doesn't do that for itself. People do that, using money as a symbolic token."
