Could you please reference the section of the Constitution that mentions "capitalism"... or in any of the writings of the Framers?
The framers/founders were big on freedom and, for the most part, owning your own stuff and being free to do with it what you want. Free markets. But the word "capitalism" wasn't around much until about 100 years later.
The Constitution doesn't name everything that you are free to do. It is more based around naming the things the federal government does, and everything not named is reserved to the states or the people.
Some quotes:
John Adams:
"Each individual of the society has a right to be protected…in the enjoyment of his life, liberty, and property...no part of the property of any individual can, with justice, be taken from him, or applied to public uses, without his own consent."
Thomas Jefferson, First Inaugural Address, March 4, 1801
“A wise and frugal government… shall restrain men from injuring one another, shall leave them otherwise free to regulate their own pursuits of industry and improvement, and shall not take from the mouth of labor the bread it has earned. This is the sum of good government.”
James Madison, Essay on Property, 1792
“Government is instituted to protect property of every sort; as well that which lies in the various rights of individuals, as that which the term particularly expresses. This being the end of government, that alone is a just government which impartially secures to every man whatever is his own.”
And so on.
