Anytime you hear someone say that the way to fix the “foreclosure crisis” is to “modify loans,” what you are really hearing is a desire for the government to destroy the concept of contracts.
People, for good or bad, made voluntary decisions to sign mortgage contracts which they, for whatever reason, cannot afford. If such a contract was obtained by fraud, there is already a mechanism in place to address this; it's called suing the crap out of them.
If, however, people voluntarily jumped in over their head, then they do not deserve the drastic action being contemplated by people like Rep. Conyers.
Why do I say drastic? Because the entire concept of contracts will be potentially voided by a move like this.
