I also find that the conclusions, if there are any, from that kind of argument are often not very useful. For example, the UK is in some ways a great place from a constitutional point of view, but that's despite having a totally crap electoral system (I usually don't bother voting: it makes no difference). What makes the UK's constitution great is the way the judiciary really is independent and really can rein in the government: https://en.wikipedia.org/wiki/R_(Miller)_v_The_Prime_Ministe...
Is that part of democracy? Probably, but it's all very vague and subjective.
