To be honest, I don't see America devouring itself whole or becoming an Orwellian regime in our lifetime, or for several lifetimes. We've been in "curious" times before, and there has usually been a backlash toward really nasty things that people do. Life, as my dad says, is better at healing that one would think, and there is no one President who could, even given 8 years, really ruin America. Sure, rising dictators have taken less than that to ruin nations, but in the US we really have checks and balances in place. Look at the Bush Presidency - four years out of six, he really screwed up - and in 2006, he was punished for it, not only by the populace voting in a Democratic majority congress, but also even his former supporters leaving him. Personally, I think the people who foresee an Orwellian regime (whimper) or anarchic downfall (bang) are fearmongers. Sure - these are hella interesting times (curse). We're in an unpopular war, Bush and Cheney are pursuing rather nasty-looking policies, and we've got to do something about the environment. Goodness, is that it? I won't say that we've had it worse, but we have had damn similar, and so have many nations on earth. Sure, we have the threat of organized terror hanging over our heads, and we're having a hard time figuring out how to deal with it. But remember the Cold War? And how it ended? We're in an unpopular war that we got into with mixed feelings, and now we're regretting it. Remember 1812? Remember Vietnam? And how we're still here? Remember McCarthy? And how people didn't like him? We got better. On a larger scale, things looked pretty bleak at the beginning of last century - World War I started for no reason at all, and one could argue that Europe is still recovering from its effects. As for the Environment - remember how they banned leaded fuels? Remember all the chemicals they've banned? Switching off of Gasoline is not impossible. It'll just be hard. And with the right leadership (which we can trust angry voters to get us), we could even turn make major environmental steps. After bad presidents, good presidents get elected. After a bad congress, the voters choose a better one. I'm not a dewy-eyed "democracy is perfect" idiot, but I can look at history and say that things turn around.
I'm not saying things aren't bad. I'm also not saying that it'll get worse before it gets better. I'm also not saying that it won't take 30 years. I'm just saying that it'll get better, because it has in the past.
Other lines of thought are depressing, and I have enough problems.
