Also known as the mortgage mess, the subprime meltdown or the housing debacle, it is the kind of financial crisis whose tentacles reach far and wide. One-part bad lending, another part bad borrowing, the credit crunch is also a case of bad intentions and bad judgment rolled into one. Lenders misled borrowers looking for a piece of the American Dream; would-be homeowners borrowed more than they could afford to pay and banks and other financial institutions turned real mortgages into securities that got traded and swapped like baseball cards.
