Rather than dividing the world between good and evil, the Left divided the world in terms of economics. Economic classes, not moral values, explained human behavior. Therefore, to cite a common example, poverty, not one's moral value system, or lack of it, caused crime.

Any economic theorem rigorously deduced from given postulates may be regarded as a hypothesis about the actual world which xperience may show to be false.
