In Government Accountability Office (GAO) publication titled "Low Defined Contribution Plan Savings May Pose Challenges to Retirement Security, Especially for Many Low-Income Worker," 2007, where Defined Contribution Play Savings is so-called 401k, and it study suggested typical mixture of the DC plan ranging for 60 - 75% of stock, and 40-25% bonds including government and corporate bonds. I don't know where you get your idea of 401 K composed mainly of bonds. Except the risk-free treasury bond, other corporate bonds just like stocks, better, but not risk-free. I don't see how you can be so sure.

May God be with you when the great depression come. Btw, even if God won't, don't worry, there will be millions of unemployed fellow Americans with you.
