It's very possible that the last 100 years will be remembered as the beginning of the collapse of a grand experiment -- representative government -- that may be completely incompatible with the human condition.
The Mel Gibson character from The Patriot (Benjamin Martin) summed it up perfectly: "Why should I trade one tyrant three thousand miles away for three thousand tyrants one mile away? An elected legislature can trample a man's rights as easily as a king can."
What you say is true; unfortunately any government will tend toward preserving and enhancing what it sees as its rights at the expense of the rights of its citizens.
I hope the grand experiment does not collapse without being replaced by a better scheme. Unfortunately, I don’t know what that might be, and neither, apparently, does John Stossel.
