This reminds me of a story I heard nearly 20 years ago. (Told by a UCLA staff member.)
In the early 2000's, a UCLA professor invited a successful entrepreneur to give a guest lecture on one of their business courses. During the lecture he was asked what made him the success and the fortune - and the answer was distilled to less than seven words: "Get lucky. Then stack the deck." He went on to explain that the best way to maintain a competitive edge was to make it as hard as possible for anyone else to try to follow his steps or to circumvent his position. But first you had to get lucky enough to afford it.
He was not invited again. Too honest and demoralising for the students.
