Taking a step back, doesn't it seem strange that there aren't more concrete answers to these questions - the debate devolves pretty quickly into anecdotes / commentators' perspectives, as opposed to hard data. Sample sizes should be big enough to at least answer the economic questions (the experience of those four years is of course subjective)!
