Optimists

Equity analysts have been too optimistic. McKinsey ran the numbers and in the past analysts have substantially overestimated earnings growth. Earnings have grown at ca 6% annually vs over 12% for the analysts' guess.
Get that 6% not more!
6% seems a lot like long term nominal GDP growth. According to BEA stat US Nominal GDP grew at 6.3% annually from 1929 to 2009 and at 5.3% annually over the past 25 years. No magic here over long period of times earnings just can't outgrow the economy.
