I say it's not possible. CRA lending guidelines were more strict than the Alt-A lending guidelines. Alt-A guidelines were "fog a mirror" guidelines and were what really caused the problems, not CRA.You're arguing the primacy of theory over data.Sorry.This goes back to what Richard Feynman once said:"In general we look for a new law by the following process. First we guess it. Then we compute the consequences of the guess to see what would be implied if this law that we guessed is right. Then we compare the result of the computation to nature, with experiment or experience, compare it directly with observation, to see if it works. If it disagrees with experiment it is wrong. In that simple statement is the key to science. It does not make any difference how beautiful your guess is. It does not make any difference how smart you are, who made the guess, or what his name is – if it disagrees with experiment it is wrong. That is all there is to it."http://en.wikiquote.org/wiki/FeynmanCCinOC seems to agree with the liberal philosophy of rejecting the empirical data rather than the theory. If reality doesn't match theory, just throw out reality.
