What is one difference between Northerners and Southerners?

The author states that there are profound differences between the two Italies, the North and the South, which make up the puzzling Problema del Mezzogiorno. All Italians share similar physical characteristics and methods for managing life, but there is a difference between the two geographical regions which has impacted the economies of each for many years and has thwarted the union of the regions just as long. Although they share some similarities, the Northerners believe that the acquisition of wealth is the way to achieve their goals while the Southerners work toward the acquisition of power and influence.
