Yes, because that means people from the bottom are not moving up. According to Aristotle, a large, prosperous middle class may mediate between rich and poor, creating the structural foundation upon which democratic political processes may operate. The prosperity of this country is tied closely to an expanding middle class. A large and stable middle class has been central to America's wealth and stability for decades; without this middle class the country's future will be in great peril.The wealthy became wealthier while the middle class and it's standard of living shrank.
Trickle down economics is a farce.
Is there really a problem if the middle class is shrinking because they are moving up? I guess what I am trying to say is that your government education is the only farce because you know shit about economics. Sorry, but I am fed up with people ignoring the facts about very basic economic matters.
