My gran, who was really poor - worked in service from age 13 - always said "if you can't pay for it you can't afford it" and would never borrow anything from anyone. Everything was repaired until she had saved enough to replace it, with the best quality she could possibly afford.
Despite that she eventually managed to buy her own small house which was unheard of for people of her class at the time, through careful saving. (no mortgage, but obviously different housing market too) Obviously if she'd had debts the saving would have been that much harder.
Anyway my point is, that if we all took her view and only bought what we could really afford, had a different view of what we "needed", would we have been better protected from the downturn? It would mean a different way of life and less "fun" perhaps, but really how much fun is all this struggling?
I know there will be those whose debts are as a result of hardship, but doesn't that just mean that they borrowed to buy things they couldn't afford when times were good only to discover, as a result of hardship, that they couldn't afford the loans either? Really most consumer credit is just that and spent on holidays, clothes, electrical goods....although fully prepared to hear about the exceptions that prove the rule
