Wait...what? The Nazis were only superficially socialist, inwardly, they were fascist-capitalists. They had quite cosy relationships with the corporate sector. On the political compass, they were certainly at the top, meaning extreme-authoritarianism, but they were not socialist.
Read Spengler's book. He is one of the greatest civilizational theorists ever. His masterwork is basically unreadable, but the book that I linked to is very readable. He has an intense pro-socialism bias, but it is easy to separate his views from his insights.
The Nazis (the specific party) were fascists, but fascism and national socialism (the generic ideology) are not the same. Fascism is an aesthetic ideology, based around finding beauty in large scale disruptions, such as industrial production and industrial war. A modern day example is Obama's first election campaign. Hope and change, masses of young people? Very fascist.

Most, probably close to all nationalists, are also ardent statists.
Well yes, because most people, whether nationalist or not, are ardent statists.
