2008 was bad because the collective banks of the US realized trillions in mortgages were money on the books that wasn't real and was never going to be real. The correction involved resetting said books and taking a few banks and a trillion dollars of US taxpayer money along the way.
What is the correction this time? All it would really be is a run on confidence in global financial markets. This has happened many, many times (and did happen in 2008 but it was a response to the insolvency of banks). It happened in 2000, it happened in 1993, it happened in 1980, etc.
If its just a correction in overvalued stocks, futures, and a contraction in loans and interest rates thats just a normal recession. We're due to have one, they happen all the time, and since there shouldn't be an influx of millions of displaced / homeless suddenly because this isn't the result of mass foreclosures on defaulting home loans it shouldn't be as disruptive this time. A lot of theoretical stock value gets wiped out, some people lose a lot of money, and then you get to start the cycle over again with rates back under 1% and the DOW down a a few thousand points from its current cresting highs.
