On the eve of the era of applied technologies, in which more and more work is done with fewer people and less effort, they made war to preserve the day of chattel slavery - the era of gang labor, with its reliance on the same use of human muscles that built the pyramids. The lost cause was lost before it started to fight. Inability to see what is going on in the world can be costly.)
