"**** it Dude, Let's go bowling."
I like that, I should rent that movie again.
Eventually america will disappear or become "inconsequential," just like every other nation-state that has existed throughout history. It probably will not happen in our lifetimes, or even out kids lifetimes; but it will happen. I'm sure the folks that lived in the Kingdom of Prussia in 1850 thought it was going to be around forever too. Regardless, I don't think I'm significantly contributing to their demise; I certainly pay enough taxes.
I agree that the perfect government would be completely invisible, but I don't think it exists anyplace either.
