I think now's a great time to buy - conditionally.
First, you have to be able to go at least 5 years to see a return of any significance, in certain industries. I don't think it's hit bottom yet, but by five years, we should see new growth.
Second, you have to be able to predict the companies that aren't going to wash out in the next two years. Normally, I'd say stick with big names and old companies; but the fact is, that's no guarantee right now. Now is a good time to examine the companies' business plans, and see who is leaning toward stable market necessities and limited risk spending, and who is banking it all on innovative but chancy strategies that, if they fail, could shut them down.
Caterpiller, for example, IIRC, is sticking to product lines and quantities that they KNOW will sell. GM, on the other hand, is in a small crisis, and is torn between sticking to their usual gas-guzzling monsters and retooling to produce more economy-friendly machines. In their case, either way, they could be in trouble. AM General, I think, has decided to stick to their usual products, but in more limited quantities - so they're not trying a risky new product, but they are still hoping that the fuel situation levels off or improves.
The point is, learn your facts, and invest with your eyes open; just popping open a newspaper and pointing is never a good idea.

As to the recession, I'm down in the bottom edges of the thing. I work at a convenience store in a very small community, so I see and hear, every day, the unemployed and recently homeless, and hear their many complaints. Jobs have dried up and vanished, taxes have risen sharply, there is no new construction (most of our remaining local industry, after all the plants have moved away or closed, was in new home construction)... it's a real enough recession.
Yet here they are, every day, throngs of people in Wal-Mart, in Ingles, at the convenience stores... It's not basic necessities they're after, either. Krispy Kremes, cigarettes, Mountain Dew (No, really, it's not a basic necessity), lottery tickets, consumer electronics, new movies, designer clothes, cheap Korean-assembled plastic children's toys...
Where does all this income come from to be disposed of so lightly, if we're in such a recession?
Then there's the fast food franchises. Oh, they claim to have slowed down a bit since '07, but every time I think to stop in at McD's and get a fish sandwich, the line is backed up to the road. There's never enough open seating at Taco Bell, either. Now, Sonic, BK, Subway, and KFC are usually pretty clear - though the KFC ought to be shut down, as often as people get food poisoning there. Sonic and BK are off the beaten path a bit, and the Subway is one of those convenience store kiosks with, like, four tables open.
Still...
It's kind of like the gas crisis a few weeks ago. Everyone was sweating things when gas almost hit $5 a gallon, but the traffic didn't thin out that much, and we still serviced plenty of SUVs and large vehicles.
So while I'm positive it's a recession - maybe even a depression - things are a lot different now, and I think we can survive even an Average Depression (maybe not another Great Depression) a lot more comfortably these days.
Whether our government survives it is another story....
