WHO'S TO BLAME???

Investment bankers are the people in our economy who sell "security" in the form of mortgages. They are ran through and protected by the Federal National Mortgage Association...otherwise known as Fannie Mae. They sell these mortgages to people and expect them to pay back. They deal with raising capital, trading securities and managing corporate mergers and acquisitions. Investment banks earn money from companies and governments by raising money through buying and selling securities. http://www.growthink.com/contact

In some cases though the investors made poor/ risky choices as to whom they were investing with. These risky people sometimes did not come through and caused some serious downfalls. Because they were reckless in trying to make quick money they didnt realize the "securities" were not secure. They poorly invested the money. Their job is to better investigate where they are doing business...(Besides the fact that they give themselves huge raises and what not...)
" Investment banks are creatures of the global capital markets. They can borrow seemingly unlimited amounts of funds from investors around the world and deploy them as they see fit." When they see fit isnt looking into the long run things begin to get a little cloudy. I personally think there are many people to blame for this downfall but investment bankers are a secure bet as a culpret. http://www.newsweek.com/id/159092
