The middle class is shrinking because:
A. Formerly middle class Americans are slipping into poverty as their incomes and wealth get siphoned into the coffers of fat cats lighting $100 cigars with $20 bills.
B. America’s families are getting wealthier; a thriving economy is producing a bigger pie, and formerly middle class Americans have their incomes and wealth swollen so much than they now qualify as upper class.
Larry Kudlow ways that the answer is "B."
