NSDAP political-economics were pretty sound.
In the early days at least.
The NSDAP were great admirers of the Co-Operative movement.
Many NSDAP members would also have been members of local consumer co-operatives.
Later on though the Nazis nationalised the Co-Ops so that instead of the members receiving their annual 'dividend' share of the surplus- that went to the Party.
The Nazis also replaced democratically elected Co-Operative committees with their own people.
Usually one Nazi ran one Co-Op.
Hence the Nazis moved away from earlier NSDAP economic models and effectively stifled the purpose of the Co-Operatives.
Co-Ops are owned by their members. German Co-Ops were ultimately expropriated from the members to the Nazi party.
