PG:  well put...... don't hold your breath awaiting that list of "pros" to our ever-increasing income disparity.  With 70% of our jobs now in the service sector and an expanding population of young people living at or below the poverty level, we are a far, far different society than I experienced as a young man (born in 1942).  I "came of age" in the period of upward social mobility.  As I look around today I see an entirely different economy with far, far fewer opportunities for young people.  That's truly sad......but, wait, "trickle down" economics will cure all woes....to use an appropriate if somewhat inelegant phrase "in a pig's #@$%" it will.  regards, Gary Crum
