All those cotton picking slaves and all the Soviet serfs weaponised into anti-working class ammunition, as they laze about the Centrelink queues.
Those 70% of the entire American working class, once involved in farming (around the 1830's) , now reduced too 3% of the American working force (circa 2016), producing X 7's more output.
All made superfluous by the internal combustion engine! Just sitting around - besides counter-revolting against the working-class revolt - doing nothing!
