The industrial revolution and the formation of unions gave rise to the middle class.
Free trade and unbridled capitalism will destroy the middle class.
One reason why the middle class developed is because companies were forced to pay a liveable wage. A lack of skilled workers and collective bargaining through unions led to higher wages and benefits.
What happens when there is a surplus of labor, and companies can have their products built by cheap overseas labor? Do you really think the middle class will continue to exist?
Where do we lay the blame?
Do we blame the democrats? Do we blame the republicans? Both parties deserve equal blame for the economic situation the U.S. is in.
