Thus, it is preferable to say: the financially incompetent person is one who does not manage his wealth properly—being cheated, deceived, and defrauded, or spending it on something from which he derives no benefit. This includes, as we mentioned, the case of one who lets banknotes fly through the air and watches them, and likewise, if we suppose that a man has become addicted to buying firecrackers, so that he buys firecrackers and sets them off.
