3. It resulted in suppression:
In the caste system the lower castes were suppressed and repressed by the higher castes. The Sudras were very ill-treated and they were not allowed to come to the public places. Even their shadows were considered profane by the higher caste people. Inter-dining and inter-mixing with the lower castes was not allowed. Thus the system was solely based on exploitation of the lower castes.
2. It stood against democracy:
The caste system ran contrary to the democratic spirit. Democracy presupposes human equality, but the caste system believed in inequality and there was a hierarchical arrangement wherein the Brahmins were at the top, whereas the Sudras were at the lowest rung of the ladder.
1. It hindered national unity:
The caste system developed a parochial feeling and made the people unduly conscious of their own castes. Many a time caste interests were given priority over national interest. Thus the whole system stood against the very concept of national unity.
