The Nazis had their economy ticking over in a very productive fashion, certainly better than before their rise. A successful economy doesn't make people behave well, although it certainly makes it easier to.
What do you mean by 'a white version of Africa'? There aren't many parallels I can draw.
Emergence of warlords/partisan leaders
(Yes, for freedom, liberty, king & country, fascism - im sure, in somalia and afghanistan they have great causes too )
Soldiers of the leash.
War feeding the war.
Refugees pouring back and forth.
Source is mostly anecdata:
My late grandfather was a Nazi truck-driver in France, Italy, eastern Europe (Hungary, Greece) and the stories he and his war companions told - are really very similar to those you get to hear from African refugees.
My grandfather and his officer made a nice little extra by smuggling people and got sentenced into a "Straf-battalion" for taking advantage of the general lawlessness of the situation.
I know, i know- the popular Nazi image in TV presents a wicked law & order extremist, but where the war went - it really was quite different. There was a mixture of total lawlessness (as in "We dont care/expend resources on subhumans") and extreme military overreactions.
And before you claim that was just fascism at work, as if politics where just a program loaded into humans, no,the unraveling usually set on before the occupation got started.
In a ironic way, the Nazis and their homecoming war proofed that all humanity, disregarding of race, pushed beyond a certain breaking point - is equally wretched and desperate.
A zombie like animal, forgetting about tomorrow, trying to see the end of today at all costs. Not a beautiful sight, but one that offers a lot to understand and learn.
The good news is, once the stress is reduced - and the war has not gone on to long, preventing the education of the next generation- there is a way to recover.
The Nazi economy was ticking over through the means of confiscating wealth from people, and later on, through just straight-up murdering them from it. It wasn't 'very productive', it was short-term gains with no long-term sustainability.
Compare the economy they had in the mid or early war to that in the early thirties or late twenties. Germany was in chaos. The output of their economy was still increasing throughout the allied bombing campaign. Duplication was removed, competition reduced, production lines simplified and available models decreased. Vulnerabilities were addressed and production went up, fast.
And yes, by every measure I can think of it wasn't sustainable, but it produced a lot in a short time with extremely difficult conditions.
