Giant corporations work hard to kill optimism. Managers lose their jobs when their sales and expense forecasts are missed by three percent or more. Then no one gets a big cash bonus and everyone is angry. Then the profits reported for this public corporation for the quarter miss by a penny and the stock drops fifteen percent that day. Investors are mad and so are employees with stock options. The most accurate forecasters then get promoted into the jobs vacated by the optimist (now gone) executives who were too optimistic.
