Perhaps the best reason to worry about Wall Street money managers ripping off investors is that most of those investors are regular people—via retirement plans. The extent of the Wall Street skim is truly shocking.

A study finds that a cheap, simple portfolio of three Vanguard index funds achieved better returns over five and ten years than almost all of the college endowments in America, which pay huge fees to hedge funds and elite money managers. Keep fuckin that chicken, smart people.

The fees you pay to invest in mutual funds are “tumbling toward zero” thanks to the growing popularity of low-cost index fund investing and, more broadly, the growing realization among average investors that well-paid Wall Street guys can’t pick winning investments any better than you can.

Last year was horrible in many ways, but it was not horrible in at least one way: for the first time since the Great Recession, we have all decided to stop handing billions of our dollars to Wall Street money managers for no good reason.

Each year, Warren Buffett—a folksy folk who has built a $60 billion fortune on pure folksiness—writes a letter to shareholders that is prized for its folsky wisdom. This year, he shares some news that even you, the poor average bastard, can use.
