Socialism and Communism were a response to the social and economic conditions that developed in Europe during the Industrial Revolution because the Industrial Revolution started a notorious economic inequity or disparity in the society. The wealthy owners of the industries became richer, meanwhile, the poor workers became poorer.
Two of the conditions that concerned socialist and communist thinkers were the low salaries that workers earned in the factories and the unhealthy conditions in which they worked. Workers labored for long hours daily under unhealthy conditions that created many risks, and of course, they did not have medical attention or insurance. The places had no ventilation at all and workers had to operate machines that created risks for the untrained workers.
