The Declaration of Independence reads like it was taken straight out of Locke's Second Treatise on Government and it is an obviously individualistic doctrine. The less poetic version of Locke's argument is that we all gain something if we give up on violence. I agree not to use lethal force against you if you agree not to use lethal force against me. I agree not to steal from you if you also agree not to steal from me. If you keep riding that train of thought, you get to a point where you can justify governmental powers on the basis that everyone can at least in principle agree and benefit from such an arrangement. The "consent of the governed" is the metaphorical consent or agreement of every single person in that kind of doctrine.
The rights mentioned below are individual rights. There is no sane way you can read "the right to life, liberty and the pursuit of happiness" in a sentence concerning the equality of all men as applying to groups in any other way than through individuals.
I read more than my fair share of books so far, but my favorite paragraph definitely comes from the Declaration of Independence:
"That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security."
I don't know how you can read this statement in context and come out with the idea it's somehow collectivist. Social contract theories such as Locke and Hobbes were rooted in the language of individualism. They were obviously replying to theories that were based on the divine rights of kings. It is also hard not to see the underlying view of human nature taken by the Founding Father. You have a case to rebel when the principles justifying existing institutions are being violated by these very institutions. However, you have to be careful not to cause more harm than good, not to cause an enormous loss in the pursuit of negligible improvements. They're saying they'll organize and do something about it, but only reluctantly and only because things are just going way too wrong.
The United States was founded by people who were mad at governmental abuses. Crony capitalism in the 18th century wasn't one of them. He definitely is reinventing history.
