Well, they'll be buying the debt for a discount. 

Probably like 50 cents on the dollar. Maybe a lot less depending on circumstances (I'm not sure how they negotiate it in these cases, might be tranches...). Whatever it is, that'll be a loss that Goldman will write down when they close that business. 

So while the debt buyer will come at cardholders fullbore, they already expect they won't recoup from everyone, or all the money from everyone. With the right tactics, you might be able to offer them 60% (for argument sake) and get a yes.

Yes, but your credit score will suffer, so still not (usually) worth it.
