Of course, but one has to distinguish between the original American conception of rights and what 97% of Americans THINK today is the American conception of rights.

The founding fathers truly understood natural law and thus laid out the "contingent" rights:  life,  liberty and the pursuit of happiness. 

They understood that the last, presupposed the second, and the second presupposed the first. 

And, that this hierarchy of rights provided a way to "resolve" contention between rights among different people.

They also grasped the proper understanding of "pursuit of happiness".  They understood it in its more demanding sense...a whole life well lived (as the Greeks taught), a morally good life.  Thus, one in this sense was never "happy" until one had run the race over an entire lifetime.

One's right to pursue this sort of life, couldn't get in the way of another's liberty, and one's freedom of action couldn't get in the way of someone's else's "life". 

Today, less than 5% get this.
