Twenty-five years later, (1) Charles Schwab had died in bankruptcy, having lived on borrowed money for five years before his death. (2) Samuel Insull had died virtually penniless after spending some time as a fugitive from justice. (3) Howard Hopson was insane. (4) Arthur Cutten died overseas, broke. (5) Richard Whitney had spent time in Sing-Sing. (6) Albert Fall was released from prison so he could die at home. (7) Leon Fraizer, (8) Jessie Livermore, and (9) Ivar Kreuger each died by suicide. Measured by wealth and power these men achieved success, at least temporarily. Making a lot of money may be an acceptable goal, but money most assuredly does not guarantee a truly successful life.
Snopes.com has an article on this story, colorfully describing it as "a vintage piece of glurge." The Snopes people maintain there's some truth to it, but that whoever first told the anecdote took considerable liberties with the life-stories of these men. There's no evidence that the Edgewater Hotel meeting ever took place. Some of the men did not hold the positions indicated in 1923. And, while there's a kernel of truth to the stories of the unhappy fates that befell them, the facts have been seriously stretched in every case.
Even apart from the questions of veracity, this one's simply old. The earliest occurrence the Snopes people found was on a printed restaurant placemat from the 1950s.
