I think the young generation is more stratified than past generations. The hardest working of this generation are truly amazing - they are far more advanced and accomplished in any area I can think of - mathematics, computer science, theater, art, sports... you name it. But many, many young people are unequipped to succeed as adults and are being left behind for any number of reasons - lazy parenting, helicopter/lawn mower parenting, single person parenting, poverty, poor adult examples, poor effort in the classroom, entitlement... again, you name it. The difference in skills, capabilities and effort between the top and rest is going to drive income disparity further than it is today.
