The far-right populist Alternative for Germany party rejects a values-based foreign policy, just as much as it rejects NATO and the US. That approach has attracted the attention of Beijing.
Again, if you have evidence to the contrary, you can contact the author of the research paper, or you can submit your findings to a peer-reviewed academic journal. Here are some further academic sources that also support the claim that the Nazi economy was heavily engaged in privatization, and some relevant quotes:
"After the 1931 banking crisis the survival of the four German great banks was safeguarded only by a huge injection of taxpayers’ money. In return, the great banks were partly nationalized and the two worst affected, the Dresdner Bank and the Danat Bank, were merged. Re-privatization was, however, started only a few years later and finalized under Nazi rule in 1937."
"There occurred hardly any nationalizations of private firms during the Third Reich. In addition, there were few enterprises newly created as state-run firms."
"The foregoing discussion is clearly corroborated by an analysis of Nazi intentions. Available sources make perfectly clear that the Nazi regime did not want at all a German economy with public ownership of many or all enterprises. Therefore it generally had no intention whatsoever of nationalizing private firms or creating state firms. On the contrary the re-privatization of enterprises was furthered wherever possible."
