An interesting editorial comment from Tanzania's The Citizen on curbing begging :
Images of children leading blind adults are now commonplace in most urban areas. There are two issues here: one, exploitation of children and, two, the indignity to those who have taken up begging as a career. It is a very crude form of child exploitation when we make a child as young as six lead an adult in a begging mission. That child should be in school, for pity's sake. Much as we sympathise with the situation of a person who has, say, lost his sight, we still believe there are ways such as person can be self-reliant. As the adage goes, disability in not inability: The late Mzee Morris Nyunyusa, blind since childhood, remains easily the best traditional drummer the country has ever produced. By the time of he died, aged 82, Mzee Morris could play 17 drums at a go. The point we are making is: Let society look into ways of helping the disadvantaged to be self-reliant. Giving them alms only demeans them.."
This is a complex issue, and certainly too simplistic to assume that beggars are exploiting their children by relying on them to earn a living. At the very least their use of their children is if anything, existential. The child depends on the begging father to live another day. But then we can't dismiss that this is indeed a form of child labour - see Children as Bread Winners. But ultimately focusing on rights here does not help unless our "rights" language is grounded in a broader understanding of "human worth". If work demeans children, we must recognise that poverty demeans the blind. The solution therefore lies in tackling the underlying causes of both : that is the denial of "economic rights" to the poorest in our society. Not everyone is a Mzee Morris, but every must have access to the basic minimums of welfare. It is the only way to resolve the difficult of seemingly conflicting rights.
