How did industrialization create new social classes as well as the conditions for the development of socialism?

Paying women half of what men received casued all of society to rebel and demand
socialism to equalize women's pay

Bad working conditions created a working class and led reformers to suggest
socialism to equalize the wealth and control working conditions

Most factories improved conditions on their own due to pressure from the industrial
middle class.

More production caused more wealth for the upper classes, who preferred socialism
in order to share their wealth with all workers
