I think that this is somewhat correct. Obviously, I don't have the evidence and haven't done the research he has done (over 800 footnotes - how many sources?!).

I think that this is somewhat correct. Obviously, I don't have the evidence and haven't done the research he has done (over 800 footnotes - how many sources?!). I do however think it could be more nuanced than what he says - it may just be that the bureaucracy changes course much more slowly than the presidency or congress or state governments change - so it takes much more time for those institutions to truly catch up with the public sentiment. Of course, once the bureaucracy begins to actively fight changing with public sentiment is when the problems begin. Those institutions that do should probably be "reset", i.e. disbanded and reformed with a better founding base.
