Worldwide governments are taking over banks to 'save' the economy. Wallstreet and other trademarkets respond by going up in recordspeed, so there seems to be a happy ending.....
I think that there is a way in which this financial crisis could be used in our advantage. If the governments decide:
1.to break down the barriers that are withholding developing countries to trade with the west
2. to only invest in companies that have sustainable policies,
there would be huge protests by those that will suffer in the short run. But the real entrepreneurs will find ways to make money in a way that will not only benifit them, but also have profits for the planet as a whole.

3. to reduce the amount of credit money and to revive (health check) longterm investments by selling or buying them back from time to time. You may win some, you may lose some, but it will not depreciate the real value of your investments.
