Caste system is a peculiar feature of Indian society. Swami Vivekananda is full of praise for the original caste system but he strongly criticises the degenerated caste system of his time. In his writings he has highlighted the problems relating to the exploitation of the poor by the rich, of the weak by the strong, of the unprivileged by the privileged one, exploitation of the lower class by the so-called higher class and so on; and the resulting struggle, the need to save people from dehumanizing poverty and a host of similar other issues. Vivekananda considers priest-craft, untouchability etc. as the main evils of the degenerated caste system. Throughout his lifetime he preaches against these and tries to generate public consciousness against these evils.
