The usual advice for people who are not on the breadline is to have at least a few months of reserves to spare. It seems we expect our national economies and business owners to operate less prudently than individual households, because we "can't afford" a more robust system.

In fact we're more than capable of creating our own recessions/depressions without a threat. And while there seems to be some legitimate concern for the current victims of this recession/depression, it's interesting how little there was during previous downturns.
