Of course our philosopher Founders knew that tyranny always works its way back in because people in power all too often succumb to special interests, which slowly bend the rights of all people toward the rights of a few. Obviously at the expense of everyone else. And the change is often subtle enough that good people let it go until the results have become too obvious to ignore. And this is when we have to right the ship once more -- one always hopes through honest negotiations.
Until now, this repeated process has had one steady factor: the players were all Earthlings. (Lest, of course, you believe in lizard rulers or other starseed options.) What we'd better get ready for, however, is the new integration of our planetary neighbors and their role in, let's say, some political machinations. At least if Darwood & Smitty has any truth to it. Either way, it's a funny and philosophical read, and especially up your alley if "freedom" is your theme.
