Check out this quote from Common Stocks and Uncommon Profits:
"As already explained, our laws, and more importantly our accepted beliefs of what should be done in a depression, make one of two courses seem inevitable. Either business will remain good, in which event outstanding stocks will continue to out-perform bonds, or a significant recession will occur. If this happens, bonds should temporarily out-perform the best stocks, but a train of major deficit-producing actions will then be triggered that will cause another major decline in the true purchasing power of bond-type investments. It is almost certain that a depression will produce further major inflation; the extreme difficulty of determining when in such a disturbing period bonds should be sold makes me believe that securities of this type are, in our complex economy, primarily suited either to banks, insurance companies, and other institutions that have dollar obligations to offset against them, or to individuals with short-term objectives. They do not provide for sufficient gain to the long-term investor to offset this probability of further depreciation in purchasing power."
