How did the evil effects of Industrial Revolution help in the rise of Socialism?

As a result of Industrial Revolution the society was divided into two distinct classes — the Capitalist and the Socialists. The capitalists had their selfish interests and they began to exploit the workers. They paid them low wages and made them work for long hours. They amassed great wealth and began to lead a luxurious life at the cost of the workers. The rich were becoming richer and the poor, still poorer. This gulf went on widening and created social disharmony and ultimately led to struggle between the two classes. The socialist took the cause of the workers and tried to save them from the exploitation of the capitalists.
