Also, if I'm not mistaken, the Dutch appeared to know pretty good what needed to be done to spur the economy - a hundred years earlier, or so.
So there must have been enough theory available - just the same infighting which keeps many countries even in our time from making the right decisions, probably worsened by widespread more or less absolutist monarchies in most of the world of that time - their leaders usually don't like reforms, and the ones who do often get removed by other people who are afraid to loose when things change.
But I think Britain might not have become quite as dominant over the next few centuries - thus making maybe the Netherlands bigger, or France. That would probably also change India's history.
If no easy-to-read documentation about economic policy was written by anyone, Prussia might not have had such a jump-start from nowhere - it might even have become part of a bigger Poland or Denmark instead. That might make Bavaria or the Rhineland the driving force of a pretty different German unification (if the Holy Roman Empire falls similar to OTL).
