Here an excerpt from an interesting article by George Friedman at Starfor.com:
What we are facing now is a structural shift, in which the middle class’ center, not because of laziness or stupidity, is shifting downward in terms of standard of living. It is a structural shift that is rooted in social change (the breakdown of the conventional family) and economic change (the decline of traditional corporations and the creation of corporate agility that places individual workers at a massive disadvantage).
The inherent crisis rests in an increasingly efficient economy and a population that can’t consume what is produced because it can’t afford the products. This has happened numerous times in history, but the United States, excepting the Great Depression, was the counterexample.
Obviously, this is a massive political debate, save that political debates identify problems without clarifying them. In political debates, someone must be blamed. In reality, these processes are beyond even the government’s ability to control. On one hand, the traditional corporation was beneficial to the workers until it collapsed under the burden of its costs. On the other hand, the efficiencies created threaten to undermine consumption by weakening the effective demand among half of society.
