My bad on the miscommunication, I was talking about "throughout history": As a result what I meant was: I can't think of any [morally exceptional people] which [past their own lifetimes] continue to improve our current day-to-day lives.
You are correct though that morally exceptional people do have a (slight) positive impact to my day-to-day. I just haven't seen a case where their contributions transcended time. Similar to the contributions of say: Thomas Jefferson, Alexander Bell, person who first repeatedly sparked fire, etc.
The contributions of religious figures transcend time. But you could argue either way about their contributions being beneficial to our day-to-day. Again it would be debatable if it was in the best interest of these religious figures to spread their personal ideology. Either of these debates would be inherently biased towards your take on religion.
And yet what you do in VFD is very often against your own self interest - you sacrifice a lot of time, and sometimes risk your health and life, and all you get for yourself is bragging rights.
Not at all! You get the knowledge that the men and women standing beside you at an emergency will be there when it's your house/barn/grain silo that goes up.
I'm surprised you ignore all those so easily.
