  As will immediately be clear, capabilities capture many more aspects of human well-being than do needs, and this is claimed to be an advantage of the approach. But it comes with a corresponding disadvantage, namely that capabilities lack the normative force that needs possess. Some capabilities (like the option of being adequately nourished) are morally important, while others (like the option to buy a fancy sports car) are trivial. So whereas a person’s being in need always counts as a strong pro tanto reason to aid them, a person’s lacking a capability may be of no moral concern at all.
