The increase in productivity due to technological change allowed for greater efficiency in the workplace, driving up wages and real income for workers. Women's entrance into the paid labor force and the end of child labor certainly played a role, but it was the increase in productivity that was the most important factor. The reduction in competition from foreign companies and the decrease in the size of the working age population do not have a significant impact on real income growth.
