The guiding principle of the Nazi state was a form of corporatism which contained elements of socialist policy. However the ideology on which the running of the economy was based was a long way from socialism.
Not really. The guiding principle of National Socialism is racism and the building of the
volkisch community. In terms of economics the main concern was to find a way to manufacture lots of weapons, for which the large corporations were harnessed. Ideologically Nazism favoured the small shopkeeper, although it did not really in practice.
In terms of workers rights' you could not call Nazism socialistic, but then you could hardly say that Soviet socialism was good for workers' rights either. Workers did get some material benefits from the regime, but to talk of socialism for Aryans would be wrong - overall consumption as a share of GDP was down and income shifted from labour to capital.
Regarding Nazi racial theory it was immensely complex, and at the same time improvised rubbish. It was believed that only the Germans were capable of producing culture. Thus it would be a disaster for humanity if Germany were destroyed. To prevent this happening Germany needed to be both racially pure and to control a vast empire so that the race had the resources to ensure its survival.
The capacity of other races to produce culture was believed to be varied, but limited - for example, the Japanese were believed by Hitler to be capable of sustaining and replicating culture but not of actually creating it.
In a sense Nazism could be thought to be international, in that the survival and prosperity of the German race was thought to be the best thing for human civilization. By definition however such an approach makes other races disposable according to circumstance.
It is worth noting that by 44-45 the propaganda of Nazism was highly international, about protecting Europe from barbarous Slavs and communists, whilst that of the USSR was highly nationalistic and patriotic.
