Thank You Sir, May I Have Another...Economic Crisis '08 Edition?

At this point, I've got to wonder whether we're psyching ourselves deeper into the hole... I hold as evidence:
"Group-think" is generally regarded as a bad thing but what would happen I wonder if everyone who's in the market just decided "$%#& it!" and "enough is enough" and put $10 back into the market today. With 100 million individual investors in the US, that's $1 billion. Might that end the slide? We can all take a $10 gamble on our futures, right? It's $10 - not that much...2.5 Starbucks lattes or a large pizza from Pizza Hut. Consider it. By the way...DOW at -$414.64 and is under 10,000 for the first time in 4 years (which means all of our gains from the same period are kaput!)... Time to double-down.
