Methinks you missed the point of the OP's argument.
There never was some glorious principled past. Crooks have been running the show since 1776, and it's nothing unique to America.
Yeah, the crazy powers the Federals have granted themselves are bad. But it's an out and out fallacy to assume that it was ever any different. We're talking matters of degree here.
The grand old Founding Fathers created a "new world order" with their little Constitution thing. Expecting future generations to honor their prejudices? Oh, well that's just the definition of optimism. Holding up a document written by dead men as the holy grail of politics is an argumentative non-starter. We all (for an expansive definition of all) wish that modern legislators would abide by the silly little social contract laid out by the the Constitution. Except the Renaissance is over, and well the ideal of a "social contract: has been thoroughly debunked,
The real problem Americans have is that they bought into the idea that a "social contract" has any meaning outside of the willingness of the current power structure to maintain that contract. The very idea that some historical document like the U.S. Constitution is supposed to be binding now and forever is naive at best.
Don't get me wrong, I want to be free just as much as anyone else, but the idea that some "ancient" document is somehow supposed to magically constrain future development is, as delusion goes, turned up to 11.
Let me be clear, our current raft of politicians are treating the U.S. Constitution as the piece of paper that it its, forget about the ideals behind the document, they don't actually matter. We've got a rather "American" problem of arguing from the premise that this grand document has any actual, physical legitimacy in the first place, let alone it's applicability to future generations.
I'm slipping into ranting territory here, so let me end this post with this: The essential problem we're running up against here is due exclusively to the naive "social contract" theory embodied by the U.S. Constitution itself. The fact that our current crop of "representatives" are supposed to uphold this contract is predicated in nothing more than the social ideal that they're "supposed to". What we are witnessing here is power doing what power does.
Go ahead, keep pretending that your pretty little "social contract" theory is anything more than an echo of the Enlightenment. Yeah, we had a good run under the social contract theory. If I were you, I would hardly be surprised that this particular contract got broken, since it was predicated on the same unrealistic ideals as our much maligned Communism.
