You mean, grow up in a poor neighborhood? I did. You mean, work for wages that put someone at/near the poverty threshold? I have. You mean, work for a company focused on serving the poor, with programs in particular for those living on the street? I do. No ivory here. We are generally successful at removing the mold and cockroaches.
I don't see the connection between this, and my statement that poorest people spend a much larger percentage of their income on things they need, as opposed to things they want.
Of course I think my values are the best ones. If I thought your values were better than mine, I would adopt your values. Do you hold to values you think are inferior?
As for moral authority, I consider the alternative to be moral bankruptcy. It's easy to forget, or not realize, just how much luck and circumstance play into our success, through no merit of our own. Further, it's easy to think of ourselves as isolated, a separate entity and ignore the various influences we have on others and others have on us. However, humanity is a highly interconnected species in reality. We earn our money as participants in a society, and it would not be possible to do so otherwise. Saying the society that made the money possible has a claim on it as well is just, not criminal.
Agreed. That doesn't change the fact that we can measure impact of not having a penny, a dollar, or a cup of coffee on a person.
