It seems to me that much of our nation's prosperity hasn't been directly the cause of the Constitution -- rather, it's been the cause of several fortunate turns of events. We profited from our early neutrality in World War I while a great many industrial nations tore themselves apart.
Geopoliticism would hold that our position made our success almost inevitable.
The number of judicial cases which invoke the Constitution is extremely low. The number of times it's invoked in every day life is so vanishingly small that anything more than a few phrases and amendments can be safely regarded as outside the immediate memory of a common citizen.
It surprises me that sometimes that so many people treat it as such an important document. More so that people attribute so much of the success of the United States to it.
