I agree lenders should suffer.
But there are some fundamental problems with how the system works. eg. banks should go bankrupt absolutely, but the people who were responsible at the banks have, for the most part, profited handsomely and likely won't suffer in any way.
The problem in my view is in the way we have states backstopping banks through bailouts, guarantees, etc either implicitly or explicitly. It encourages recklessness because there are benefits if it pays off and no personal downside if they lose. It is like going into a casino where someone says they will backstop any losses you have. Without any guarantees that my losses will be given back to me, I will only bet a small amount. With a guarantee to pay my losses I will bet the house because it is all upside, no downside.
The debt jubilee? Just imagine if everybody in this country who was in debt had it written off tomorrow. Would that be fair? Would it be fair if the guy living next door who racked up massive credit card debts buying all the things he wanted while you were prudent suddenly had his debt written off. It would send the message that the reckless benefit and the careful and prudent suffer in comparison. Can't agree with him on it.
