Okay, fair enough, and I am by no means intending to criticize you for your kindheartedness here, but that’s literally the opposite of economic theory, which concerns itself primarily with achieving the maximum output possible given a certain input.
Also, consider that this does not mean that it is therefore by nature entirely inhuman and incompatible with caring about people, but rather that the ability to achieve a high productivity is required in order to have an excess of resources than can be used to care for those who cannot care for themselves.
If you think about it, this is in fact essential to maintain human life. Children for instance always require more resources than they can produce, so parents have to be able to produce more than they need for themselves if they want their children to survive. Same goes for society as a whole — the productive members have to be able to produce an excess or the unproductive (weak, sick, or old) will starve.
