Do you think our economy is going to crash?

Here's the thing. I've only been investing for about two months now. In the two months I've been investing, I've seen the market top out at 14,000 and then slide up and down wildly and almost without warning. At first I had no clue what the heck was going on. Then a couple of days ago, my fiancee told me that her dad lost his job as a homebuilder. That pretty much summed up everything and put the market in perspective. If something isn't done to help those that are going to lose their homes and increase liquidity for mortgages, I think the economy goes from perhaps mildly inflated to a rapid deflation. I'm not saying we'll see an outright depression, but it's not going to be good. It's definitely not as easy to make money as it was at the start of the summer. The problem is I haven't been in the game long enough to understand everything that's going on.
