Thats the case with any mortgage with a high balance, in trouble or not. In fact thats the whole point. The lenders get the bulk of the payment they would have received anyway, but from the government.
Look, the governments going to spend the money anyway- whats better keeping people in their homes, with some cash to put in the economy, or dumping it into Boondoggle, worthless, porkbarrel "public works" projects that only benefit a handful of people?
