Nah, don't think so. Keynes might not have been right about everything but I think some of his ideas are the closest we've come to what could be described as a 'just' economy. Indeed if we're going down this road then the broken window fallacy contains a contradiction (and so must be false) because it assumes full employment to reach its conclusion. Something that, should it be true, would probably cause the problem we're trying to solve to disappear.
