The world’s first automatic conveyor belt escalated the Industrial Age inspiring Henry Ford toward an unprecedented $5 per day minimum wage and an eight-hour day when auto industry workers were making $2.34 for a nine-hour shift. Faster assemblage meant quicker availability, giving impetus to America’s car culture and an ever-increasing mobile society. (AP Photo/Ford Motor Company)
