Today, no work is lowly if made profitable. Humble barbers can become internationally renowned hairdressers. Scavenging is considered the lowliest work. Now sewage disposal and recycling of waste is a big profitable industry in which private companies are muscling in. For centuries, balmikhis have been the scavengers in Indian society.
Indian castes are vocation-based.
Many of the vocations have become big business. Caste is a reality in India, but it need not be a weakness. But talking advantage of century-old vocational traditional, we can turn it into a national strength and revive the craftsman's pride in his job.
