What if I told you that medical/accident/disaster expenses (even just counting deductables and co-pays when insured), are not "borrowed to live a comfortable life" but are treated by the credit system the same as unbridled credit spending?
Even the better - someone who has decided that he really doesn't need to ever borrow money has no worries about any credit ratings, so borrowing $20 000, 'defaulting' and paying $10 000 to cover the loan would be completely free legal money with no practical consequences.
