This week the finance world lost John Bogle. He was the founder of Vanguard and the “creator” of what we now call index investing. He was the most important figure in investing. Most everyday investors have never heard of John Bogle yet his impact is felt by almost every investor. Wall Street told him an index fund wouldn’t work. Wall Street told him low cost investing couldn’t work. He proved Wall Street wrong and all these years later every traditional mutual fund company is rushing to compete with index funds and ETFs. The amount of money he indirectly saved investors is well into the billions (and maybe more).
