Wondering how much you should give to charity? Peter Singer has some pointers, based on his classic example of how much we should expend to save a child drowning in a shallow pond.
In any case, even if we were to grant that people deserve every dollar they earn, that doesnâ€™t answer the question of what they should do with it. We might say that they have a right to spend it on lavish parties, private jets and luxury yachts, or, for that matter, to flush it down the toilet. But we could still think that for them to do these things while others die from easily preventable diseases is wrong. In an article I wrote more than three decades ago, at the time of a humanitarian emergency in what is now Bangladesh, I used the example of walking by a shallow pond and seeing a small child who has fallen in and appears to be in danger of drowning. Even though we did nothing to cause the child to fall into the pond, almost everyone agrees that if we can save the child at minimal inconvenience or trouble to ourselves, we ought to do so. Anything else would be callous, indecent and, in a word, wrong. The fact that in rescuing the child we may, for example, ruin a new pair of shoes is not a good reason for allowing the child to drown. Similarly if for the cost of a pair of shoes we can contribute to a health program in a developing country that stands a good chance of saving the life of a child, we ought to do so.
