Which of the following was NOT a consequence of industrialization?

The decline of the working class was not a consequence of industrialization. In fact, industrialization led to the expansion and growth of the working class as more people migrated to urban areas seeking jobs in factories and industries that flourished during this period. Workers were drawn to emerging employment opportunities in manufacturing and related sectors, which created a substantial and often challenging environment for laborers.

As industrialization progressed, the workforce grew, leading to significant social changes, including urbanization, the rise of labor movements advocating for workers' rights, and increased scrutiny of working conditions. The other options accurately reflect key consequences of industrialization: urban areas expanded rapidly due to the influx of job seekers, mechanization boosted agricultural production by enabling farmers to cultivate more land and produce goods more efficiently, and the demand for cheap labor in factories resulted in the unfortunate increase of child labor.
