How is it "the responsibility of business to maintain a strong middle-class"? How is it that business is creating a "new elite class . . . while the middle-class is reduced to serfdom"?
Private businesses have no responsibility to do anything with a view towards the larger economy. Private businesses are obligated to obey the law and create profits, nothing more.
If every private business did nothing more than obey the law and make a profit, our entire society would be better off. To the extent our economy is healthy today (and it is) it is the result of free-market principles. On the contrary, our greatest economic failures have been when legislatures or activists have tried to impose other (non-market) obligations on business.
Today's middle class in America is the wealthiest in history. Even the poor have cell phones, air conditioning, television and the Internet.
By contrast, only a few decades ago the poor lacked indoor plumbing, electricity and enough food to eat.
How can you possibly claim that anyone today is "being reduced to serfdom"?
you mentioned "obey the law" several times.
U.S. "free-trade" agreements with 3rd-world-like countries are a way for U.S. business to subvert U.S. labor and environmental laws. it is not an even playing field.
even w/o free trade agreements the cheap labor and lack of laws to "obey" make places like China so agreeable to U.S. businesses.
i have nothing against walmart, big businesses, or the upper class but i can still see the obvious. if all of the products walmart sold had to be manufactured (etc.) in accordance with U.S. laws and regulations there would be no walmart.
