Well they should have thought of that when all of these make believe securities were invented.
The Banks have proved themselves completely inadequate in any kind of Fiscal prudence whatsoever. They turn up and ask Mummy and Daddy to get them out of trouble and now want to squeal like the spoiled brats they are that Mummy and Daddy want to ground them for stupidity.
I am sure Mummy and Daddy will let them out to play again one day when they prove that they are actually able to play nicely in the world.
Lets not be frightened - selfish greed has brought the world to this mess and now controls need to be applied - lets celebrate and get on with life.
