Interest only is OK provided you have a GUARANTEED way to pay it off when due. Most people don't which is where the problems lie.
The current situation is - in many ways - long overdue in coming. Endowments screwed up my generation and now we've got the second recession in a matter of twenty years that could wipe literally billions off the face of the economy. Labour has managed to spend everything that we had, so the UK (along with the US) is effectively bankrupt.
If the political liars were serious about actually doing something to help, they'd take 20p off the fuel taxes now and avoid 90% of the looming problems, but greed overcomes sensibility and we're all paying for Gordon's stupidity and fiscal mismanagement.
SHARK!
