Munger: "One of the smartest things a person can do is dampen investment expectations, especially with Berkshire. That would be mature and responsible. I like our model and we should do nicely."
"The problem is the starting point in predicting modest returns for equity investors. [Expectations were too high.] In 1999, a Gallup poll showed people expected 15% [returns from stocks] in a low inflation environment. In a low inflation environment, how much will GDP grow? If there's 2% inflation and 3% [real] growth, that's 5%. This will be the rate of corporate growth, so if you add dividends, you get 6-7% [annualized returns] before frictional costs -- and investors incur high frictional costs (they don't have to, but they do) -- which adds up to 1.5%. [This 4.5-5.5% is] not bad." by Warren Buffett
