It's not a tough problem. Think about it this way. Imagine you and your mom, your wife , your siblings are born and lived in a poor country. And they get sick. Will you want to save them because they deserve to be alive? Or will you want to let them die just because they could be a burden to the already poor society. Just let all loved one dies? How difficult it is to answer this question? Oh, that's because it's somebody else's moms so just let them die so that the society has enough resources for the rest?
