I'm torn. Certainly it's important to have financial market stability so people can trade and not have to worry nationwide about defaulting mortgages. But on the other hand, a premise of capitalism is that companies succeed or fail based on their decisions and potentially become lax or dependent if government steps in (people who know/remember the Savings and Loans scandal back in the 1980s are not surprised that banks once again created a financial disaster by trying to make a fast buck and ignoring/downplaying any risks involved, straying far away from their traditional, conservative role).
If there's one thing I'm certain about, it's that 15, 20, 30 years from now, people on Wall Street will forget the disaster and the lessons, and once again cause financial/market turmoil just because they're addicted to easy money/huge profits and ignore/downplay risks. People never learn, and constant government bailouts will only reinforce this lackadasical attitude/safety net entitlement belief.
