The word capitalism does not appear in the Declaration of Independence, nor does it appear in the United States Constitution. In fact, capitalism as defined in the modern convention is an economic system of which businesses as well as individuals own goods that they produce, manufacture, or create and thereupon sell those goods to other businesses or individuals, at a profitable price point that is agreed upon by the parties to that transaction. That said, it wasn't until the mid 19th century, that capitalism, as a word was even utilized, and capitalism as a word didn't start to become into somewhat common usage until far into the 20th century, which signifies that clearly America was never formed for the express purpose of capitalism, whatsoever; though most Americans, today, see the United States as a de facto capitalistic society.
Now, of course, some might argue, that words both fall out of favor and into favor, and although capitalism as a word didn't exist back at the inception of this nation; nevertheless, still in principle, this country, has always been about free enterprise, free markets, and about business, above all else. Yet, the word corporation does not appear in the Constitution, and in fact, the word business appears only just once, and this in the specific sense of the need for a quorum of congressional representatives that have to be available, in order to transact legislative "business". So then, it appears that America wasn't founded upon capitalism, nor was it founded upon business, yet, somehow, modern day talking heads, are insistent upon the belief that the "business of America is business".
The reason that capitalists and businessmen are so obsessed about business above all, really comes down to the salient fact that they are obsessed about making money, above all; and therefore want the American public to believe that there isn't anything more important than the necessary conducting of business to make money, for money and profit apparently makes everything, better. While, that might very well appear to be true for those that are capitalists, it isn't what this country was actually founded upon. Instead, it would be more accurate to state that rather than this being a country based primarily about business and the making of money, this country, was in fact, established upon the equality of mankind, freedom, liberty, and unalienable rights for all.
When Abraham Lincoln gave his Gettysburg Address, what he did not bother to mention was any word having to do with business; instead, he wished "…that this nation, under God, shall have a new birth of freedom…" which is exactly what this country was meant to have from its inception. This freedom of speech, this freedom of the press, this freedom of assembly, this freedom of movement, this freedom of person, this freedom of choice, and this freedom of liberty, is the essence of America at its inestimable best. To the degree that this country honors those freedoms, it honors what this great nation was founded upon. So then, to the degree that capitalism contributes to that freedom, so much to the good; and to the degree that capitalism does not contribute to that freedom, this so represents the fundamental problem and enduring error with any system of enterprise that in its implementation comes to the place where it supersedes or compromises that unalienable freedom of the people, by supplanting such with the lust for money and profit, above all else.
