A propos of which, I offer this quotation from John Kenneth Galbraith:
To the economist embezzlement is the most interesting of crimes. Alone among the various forms of larceny it has a time parameter. Weeks, months, or years may elapse between the commission of the crime and its discovery. (This is a period, incidentally, when the embezzler has his gain and the man who has been embezzled, oddly enough, feels no loss. there is a net increase in psychic wealth.) At any given time there exists an inventory of undiscovered embezzlement in - or more precisely not in - the country's business and banks. This inventory - it should be called the bezzle. It also varies in size with the business cycle.
