Anyone who is serious about investing knows Jack Bogle of Vanguard legend. I always admired his straight shooting style. I have great admiration for such candor. These traits are often in short supply in the investment world.
John Bogle is best known as the "cheerleader" of the index fund. He has built Vanguard from a small company to one of the largest financial companies in the United States. Like many small firms that have overtaken gargantuan competitors, Vanguard continues to leap ahead by giving their customers a fair deal.
In his book, Bogle provides a bevy of information about the financial industry that many investors are unaware of. This is an essential book for investors.
