My humanity is more important to me than others. I have to take care of myself because I know others would resent me if they had to take care of me. I'm sure you wouldn't be thrilled to provide for me if I came to your house with my hat in hand.
And you feel the same way - we're just arguing over where to draw the line. If you save any money that could be donated to those in need, you've also put money above humanity. Have you ever bought a Mcflurry? Did you really need that sweet treat more badly than someone needed a malaria net?
So where's the line of sociopathy? What's the permissible amount of money to put above humanity?
