Origin of social evil 'untouchability'

Untouchability has been practiced in the society for a long time in developing countries like:Nepal, India and other backward countries which has become one of the most common social evil. It has been practiced in some backward societies by backward and conservative people.

In the past, The people, who could earn more money and become rich , established themselves supreme. The people who involved in poorly paid professions could not establish themselves as the normal people. They became poorer and poorer because of the egoism of the rich, they gradually started calling the poor the 'untouchable' . The poor could not raise the voice for their rights. Gradually the practice of untouchability was established in the societies, and it has been in practice since then.

The oppressed may start destructive struggles against the social structure; and it ultimately invites hatred, hostility, betrayal, brutality, and so on among the people. They cannot enjoy human rights. The practice of untouchability stops people from building up fraternity among them. It also stops people from being virtue to uplift human civilization.
In order to raise the socio-economic status of the untouchable, particular programmes should be implemented. It is realized that the organization established in the name of untouchable cannot raise their status; rather they are registered untouchable for ever. Therefore, such organization should be reformed.
Therefore, such social evil should be removed from the society as far as possible. Because untouchability is one of the most deeply rooted evil performed by a people who think untouchability as an slogan. In this twenty first century, also don't follow such social evil 'untouchability' which stigmatized our identification and dignity. I request all of the people or viewer not to perform such bad social evil 'untouchability' . I hope u will not will u ?
