The Economist says the game is up:
The old-fashioned financial system was like Old Maid, a parlour game once beloved of small children. The banks were like players, dealt hands from a pack of cards, which they swapped among each other. At the end, one player was left holding a lonely queen—a bad debt, if you will—and lost. Over the past few decades the game has changed. Securitisation has snipped the old maid into pieces; new faces, such as hedge funds, have joined the party, enabling the banks to distribute those pieces among a larger number of players. When the game is over, lots of players are left holding small losses instead of one player holding a big one.
[...]
At the end of Old Maid as banks used to play it, the loser would take a big write-off and then everyone could start playing again. In the new version, the use of leverage means the game is being played with hundreds of packs of cards and by thousands of different players. Working out who has won and who has lost in this round will take a long time.
