The one thing that never changes is that the rich get richer, and the rich are always devising means of increasing their wealth.
Take this sub prime mortgage crises that we imported from the states. The banks are supposed to have lost billions. If you believe what they tell us you would think that every payment defaulter had had their house burned down.
If someone can't pay their mortgage the house is repossessed and sold, houses that were purchased years ago can't all be in negative equity, the only possible actual loss is when the property is sold for less than the outstanding debt, and even then they don't let the debtors off the hook, unless they actually go bankrupt the debt will still have to be paid.
The problem that is inherent in the system, is that the banks borrow money to lend, this money is borrowed from the multi national rich, when these call in the loans the banks have to sell off assets at knock down prices, these assets are of course bought up by the rich.
It's easy guys, you sell a van to Joe the window cleaner for 2 grand, you then make sure he breaks a leg and can't work, you buy the van back for a grand, and sell it on for £1.500.
Only the rich work on a far bigger scale, but one thing is certain, they will become richer. Dai
