Money & Happiness - Where Money and Morality Meet

Recently, in the class I teach at Seton Hall University, we were discussing the characteristics of a morally mature conscience. What qualities or attributes would you find in the conscience of, say, Martin Luther King Jr. or Mother Teresa?

What would be the critical cognitive powers, the emotional intelligence, and the virtuous habits of a moral giant? (I highly recommend such ponderings at 8:30 a.m. It beats the pants off morning television, with no commercial interruptions.)
