17 May 1792: Brokers sign the Buttonwood Agreement
On May 17, 1792 two dozen stockbrokers signed a short agreement, traditionally said to be under a buttonwood tree on Wall Street, to trade only with each other and charge fixed commissions. It was the seed of what became the New York Stock Exchange. The first rule of American organized markets, in other words, was about protecting the brokers' fees, a tradition the industry kept for 183 years.
The lesson: Markets were built to serve investors, but the intermediaries have always made sure to serve themselves first.

What S&P 500 index fund teaches: Owning the whole market removes the risk of picking the wrong company but not the risk of a lost decade, so time horizon matters as much as diversification.
