How did russian industrialization increase the revolutionary movements?

During the reign of the czars and the proliferation of feudalism, most of the people were poor farmers with little say in their jobs. When industrialization happened, those poor people began taking the factory jobs and working for very little pay in terrible conditions. Yet now these people were now in a concentrated area and had a much better chance to talk and organize. They had many shared grievances and were able to talk out against those in power and increase the revolutionary movements.
