I know there are intangibles, things like morale, belief in one's country and cause; but in terms of provable things (industry, manpower, etc) how much stronger was the united "German Empire" compared to the smaller "North German Confederation"?
If the NGF had managed to, through some quirk of Alternate History, survive to WW1, how much of a difference would we have seen if most of the other decisions (like where to focus on in terms of economic growth) had remained the same? If the South German states had remained Neutral, would North Germany alone have been able to hold up as well as Germany did? If the South German states had joined the war, would the lack of "Prussian Leadership" mean the whole is much weaker than in our timeline?
In particular I'm interested in things that can be easily shown and proven, statistics and numbers would be great, as I already have a bit of a grasp on the psychological impact having "only half a country" would have on it's factory workers and fighting men.
