Bad analogy , you're speculating on what he's doing , what are you doing? maybe he does give money to charity do you? ( before you ask I do ) lets say he didn't who cares? Jay is successful so he's responsible ? lets say you do give money to charity why do you care of Jay doesn't?
I was showing that a person not doing what is right, or 5 people not doing what is right, or a million people not doing what is right (saving the drowning baby and/or solving social problems such as hunger), does not justify us throwing our hands up and saying "well since they aren't helping, I wont either". So the point is that it doesn't matter what others are doing. Comparing oneself with others in terms of contribution doesn't relinquish the responsibility of contributing. That answers your first.....2 questions, and partially answers the 3rd and 4th.
If you saw a baby drowning and were standing right there, and watched him drown, I think it's safe to say that you are a morally bad person for not helping. What if the baby was 2 feet away, what if the baby was 3 feet away, 4, 40, 400, etc. Same with hunger. Why does distance relinquish responsibility? Because hunger is in Africa, and Jay (symbolizing those that live well beyond their means purely for their own ego satisfaction) is far away, he is not responsible for helping? By that rationale, if Jay (or a similar person that claims they aren't responsible because the problem is way over there) was standing beside a starving baby, if he took off running fast enough, he would no longer be held responsible for not helping.
I'm just using Jay as a symbol for people that live unnecessary beyond their means. I'm moving away from using Jay as a person, because I dont know how he is.
If it helps any, I"m just using the argument of Peter Singer lol.
