Firstly, it may well be the case that we are indeed morally obligated to donate all of our disposable to charity; the longer one considers how many people could be saved with the money one spends on a flat screen television, the less acceptable the purchase becomes. However, there are also meaningful distinctions between the thought experiment and donation to charity. In the thought experiment, there is no one else who can possibly come to the aid of the five. This is distinct from the complexities of a global economy where there are other possible moral saviors and the path to saving lives is far less clear.
