Let me in conclusion give you the example of a blind person who is employed as a teacher in a school for the blind in a small town in India. In his spare time he visits slums where he motivates children to get enrolled in schools, gives them tuition if necessary, arranges to get them text books and other educational material, promotes adult literacy and teaches crafts to the women with a view to helping them to earn some extra money. All this is on a purely voluntary basis for which he receives no payment. In many of the slums he is accepted as a friend. He is not regarded any longer as a poor helpless blind person but is now treated as a much respected member of the community.
Disabled people are a large enough section of the human resources of any country.
They can be converted from tax consumers to tax payers, from beneficiaries to benefactors, given the opportunity for self-development and provided with equal opportunities for education, vocational training and employment.
