Well, my first post which was trashed (rummage around in the trash can if you care enough to read it) was actually a reference to a video game. In the game, this group of people (cat people) think that if these ridiculous prophecies come true then the world was ending. This Demon Prince of Madness hires you to manufacture these things in order to essentially drive the population insane, and because he thinks it’s hilarious. So, that’s my answer to unreasonable gloom and doom scenarios – flaming dogs falling from the sky.
In the allegory there is a message though. A lot of messages actually. People will believe whatever they want and find evidence to back it up, no matter how nutty the whole thing might be. I get the metaphorical impression here that some see the signs they made coming true and that some see someone behind the scenes doing all this for some dark unknown malevolent purpose. It fits into my overall theory that all prophecies are self-fulling. Meaning, if I say that the end of the world will be marked by flaming dead dogs flying from the skies, then someone can launch a whole bunch of them into space and let them fall down, thus fulfilling the prophecy. Or they can say that the dogs represent crashing planes, like in a war. Someone is going to make happen what they want to, or going to find a way to interpret the events to match the prophecy.
This same thing could be said about predictions in general. That’s why it’s important to make it clear what you’re actually predicting and why – like I did here. I wanted to bet against the odds, and I wanted to test the predictions market here. I definitely didn’t make the right prediction, but I’m not going to go back and pretend I said anything different.
It’s relevant because if you make the prediction like “the economy is going to hell because of Obama” there will be a tendency to look for signs to match that and only that. One could ignore any positive signs or anything to the contrary. One might be determined to think this, so thats all one can see. Having to deal with these issues on a constant basis I can say with certainty that economic issues are hardly ever what they seem. I had a professor who said that economy issues are like onions, people take the wrapping off and just assume what there is all there is without really going into the layers.
Speaking of which, I could go off calling all the people saying “it wont be that bad” Obama supporters, quasi-Objectivist, or something similar to make a huge hyperbolic point. But, it’s going to get lost.
Instead, I’ll do what adrock did,
* Time Magazine’s Man of the Year: Barack Obama
If I’m not mistaken, pretty much every President of the United States has gotten this distinction ever since it’s been done. That’s like saying Obama will eat breakfast at the White House during his administration. It might not happen, but even I’m not betting against those odds.
* Islamic terrorists will hit America hard, perhaps with Iranian nuclear devices, wiping out between 100,000 to 10,000,000 Americans
First off, where is your evidence for this? It’s what’s to be expected but, why? Because a new president is elected doesn’t mean that military, the CIA, FBI, NSA and others just disappear. It’s funny you mention Iranian nukes, because this administration doesn’t seem to want to let Iran gets nukes, or anyone else for that matter.
* Super inflation for consumer goods
That depends largely on the actions of the Fed, which is (at least somewhat) independent of the President. If Bernanke and Paulson want to run the mills like the Weimer Republic that’s their choice. But I don’t think they are that ignorant. This administration might spend a lot, but there are other ways to get the money then (basically) printing* it.
Also, what could cause “super inflation” is the break out of war. Although in recent years we’ve seen some similar levels of inflation without the wars, it’s still rare and it’s still war that usually provokes inflation. Ending our current engagement in Iraq would/could/should actually help slow down inflation (as would some other things, but that’s too long to get into and you can probably take a guess at it.)
* Destruction of domestic auto industry by government forcing US auto makers to make cars most people do not want to buy
Again, as adrock pointed out, this has been happening for years already. It’s not going to be any different in the next 4 years and if it is (as in it the government stops) then I think everyone will be shocked.
* Increase in income, capital gains, dividends, corporate, estate taxes
That could go either way actually, has there already been a proposal to increase these things? If not we can just sit back and hold our breaths.
* Greatly expand number of citizens dependent on government for survival
Well, the same thing was said about Clinton and he reduced the size of the welfare state. What makes you (or anyone else who feels like responding) think this exactly?
* Rise of political entrepreneurs as market entrepreneurs withdraw from society
This is an interesting observation actually. I’ve noticed the only entrepreneurs who go into government are the ones that totally failed or the ones that are very ideological and principled, who’ve tried their hand at running a business and now want to run a government. If we get more of the latter, that might not bad. But, already government has a lot of those “failures” in it’s midst.
* Curtail military while expanding entitlement programs
Again, where is the evidence for this?
* Silence political opposition via Fairness Doctrine, Hate Speech laws, approval committees for radio stations
To the extent of my knowledge the Fairness Doctrine doesn’t make political opposition cease, it just demands that opposing view points are presented on controversial “public issues”. I’m sure this isn’t going to stop guys like Rush Limbaugh.
Also, since the ARI opposes just about everyone on the radio today, maybe this can give them a big break!** 
* And finally, blame Bush for society’s ills
Society is already doing this, and it will continue, so you’re right! Everyone from all over society is blaming Bush, even his own party. An Obama/Reid/Pelosi run government isn’t going to change or stop that.
In conclusion, I know Fireball won’t respond to these posts because he doesn’t do that. Recent record shows he makes these posts and leaves us to argue amongst ourselves about them. A fireball that starts flames? I wonder. I’m going to go with DavidOdden on this and say we should dredge it up in four years. On that note, I’m still waiting for Bush to declare himself king! 
*This is a simplification for the sake of simplicity
**This is a joke.
