Strategy Follows Structure
Bogle's most quoted line on Vanguard is not about index funds or fees. It is about governance. 'Strategy follows structure,' he would say. By designing Vanguard so that the fund holders were also the owners, he made low fees the only rational outcome. The board of directors elected by investors would always vote to lower fees when they could, because doing so was in their own financial interest. There was no separate class of shareholders to disappoint. This is the thing most people miss about why Vanguard's fees are low. It is not discipline or virtue or competitive pressure, though all three play a role. It is structural inevitability. Every time Vanguard lowers its expense ratio, it is the functional equivalent of a normal company reporting higher earnings. The surplus gets returned to customers, just without the taxable dividend event. At 0.07 percent average expense ratio today, compared to an industry average of 44 basis points, the structure is still doing exactly what Bogle designed it to do fifty years ago.
