Andres:
Wealth need not be acquired "at the expense" of others. The problem with a large wealth gap is not that some are filthy rich, but that it tends to stultify the "have-nots" ability to become "haves." Absent a credible -- if difficult -- means for changing your status, you get the kind of class rigidification that yields bloody revolution -- during which the "have-nots" victimize their own more than the "haves."
