That is a pretty loaded assumption about the superior financial security of the knowledge worker. It seems clear from the numbers of developers being laid off and start ups that are financially failing that this assumption is imaginary. The only financial security a knowledge worker has, in this current economic downturn, is the essential nature of their employer or their employer's cash liquidity.
