Successful capitalistic democracy requires a moral foundation.  Many things that are arguably "in the best interest" of an individual are not in the best interest of a functioning economy, and not honoring one's agreements is one of these.  The fact that corporations are not being ethical does not justify on a moral basis the same behavior by anyone else.<p>Further, if the coming predictions of high inflation turn out to be correct, the people who are still holding their mortgages will be paying them back with cheap dollars vs. people who walk away from their current debts and then need to borrow again later.
