Americans have lost trillions -- with a "T" -- of dollars in the stock and housing market collapses. The average person with a 401(k) plan has lost five years worth of their savings! No wonder people are nervous about whether they have enough money saved for retirement. Today, Ken and Daria Dolan of Dolans.com have a surprising answer to the question "How much money do I need in retirement." The conventional wisdom is dead wrong, they say -- listen to it and your retirement dream could become a nightmare.
