My friend, I am afraid you are in the wrong business. You see, traders are in this business to trade. When 9/11 happened, the markets opened up days later and you have to trade through it and assess the impact of it on companies and general conditions. Trading is a business, and that's the cold brutal truth of it. Don't get me wrong, traders are humane just like everyone else. We grieve for losses or catastrophes that happen, but we also never let it get in the way of clear market judgment. It's not disrespect at all, you pay your respects and you let it go - sometimes you can't help situations, and usually it's always better to contribute if you have extra money for the cause. When Chernobyl happened, you can bet traders were assessing the impact it would have on global agriculture markets.
I also fail to see why it is bad taste for an economic meltdown. I'm young and poor, but I understand that the economy works in cycles. If the economy is expanding and inflationary for too long, that's a bad thing too. Deficits have to be paid for eventually, and we only borrow against the future.
If it happens, it's going to be out of my control. What I CAN control though, is whether I'm positioned to profit from it so I don't get my stake wiped out.
Anyways, an economic meltdown isn't so bad if you think about it. To build up new muscles, you essentially tear down the old ones and build new ones in its place. The economy is no different. The great depression brought along increased government regulation, ingenuity, and essentially the "welfare state" (Although, I'm not arguing this is all a good thing, I'm more along the lines of proposing that an economic breakdown causes drastic changes).
