Well people once upon a time believed countries could not survive without colonization and slavery. They believed accumulating gold was the only sustainable path and therefore all resources in the economy should be devoted to exports. Obviously what comes out of a 3 inch chimp brain as it reacts to complex dynamical systems too large to fit or keep updated within said 3 inch space, should not be studied too religiously. The path of the hurricane is not controlled by the chimp. We just learn coping mechs and story gen to hide our limitations in controlling some systems. The debates are part of the cope theatre and a waste of time and energy.
