You're making an emotional argument. Let me try. Why are you condemning the single mother whose job has no access to mass transit and who can't afford to live within walking distance, who therefore has to drive a death trap and endanger her life and the lives of her children?

The problem is that we have limited resources. We can't save everyone. And making emotional arguments gets in the way of doing the most good. Why is it better to spend money on nurses to change the bed pans of the mentally ill than to spend it giving opportunities to those who want to go to medical school, who may one day ultimately cure them?
