We recognize the Founders for having the courage to throw off the yoke of an oppressor, and succeed. We honor them for then in the same lifetime laying out a blueprint of government that has reasonably withstood the test of time and managed to remain flexible in spite of some serious adversity.

Is it showing it's age? Probably, Is it long overdue for a strong reaffirmation? Probably also. Does it instill in any one particular dude the absolute unquestionable right to rule over anyone else? No. No it doesn't.

The American Experiment, though the institutions of today hedge more on the side of "we'll be the judge of whether you can do that" was fundamentally a novel effort at it's time. It enumerated the Governments specific powers and limits, then dumped the rest of the power in the people to do with as they will.

Completely different beasts.
