This podcast episode was originally released in September 2022. Eric Balchunas got to know Jack Bogle through interviews with him and conversations with more than 50 people who worked with him over the years. The result is his new book, The Bogle Effect, where Eric chronicles the serendipity that marked Jack Bogle's career, from his ouster at Wellington to the creative approach he took to starting Vanguard and the unique way he structured it (as a mutual company). If you invest in mutual funds, you have Jack Bogle to thank for driving down the costs of the industry and for popularizing the lowest-cost mutual fund of them all, the index fund. Eric also shares his favorite personal finance resources and important investing lessons he would share with high school students. Enjoy!
