I would say the target audience, those that he really wanted to step back and think about their suggestions were his fellow pamphleteers and those of the upper class. I think he had plenty of success after the fact. I do not think the middle class of the times had as much leverage as we think of the middle class. During this time of such brokenness for the country it was evident that those who were less fortunate were essentially at the whim of the those in power. Now if you mean success as in people actually taking his suggestion and running with it, I highly doubt anyone but the very rich and powerful would have even remotely agreed to that kind of suggestion.
