I think "credit crunch" is a misnomer, but shorter and easier to say than "banking collapse through reckless behaviour in a desire to become unbelievably wealthy". But thank the Gods that Governments (and us as tax payers) throughout the world are bailing them out in what amounts to socialism for the rich!
O London, see
Swelling with naval pride, the pride of thee!
Wide, deep, unsullied Thames, meandering glides,
and bears thy wealth on mild majestic tides.
