I disagree with the idea that Hitler “seized” power.
The NSDAP presented itself as the only alternative to the failed parties of the Weimar government and enough people voted them into power that they were able to form a government. It is of no small irony that no one has ever accused the Nazis of rigging the elections they participated in...unlike the Democrats.
The NSDAP improved people’s lives and that helped them to gain more power in an open electoral process. They were definitely socialist and they also established a welfare state that was celebrated by American leftists.
When Hitler ordered the German army to retake the remaining territories occupied by the French and Belgians his personal popularity soared and when the NSDAP consolidated political power by making the chancellor into a dictator the move was celebrated by most Germans.
In short, he did not ‘seize’ power although some people feel better about themselves if they think of it that way.
The Nazis also formed alliances with large companies to control but not own the major industries. They heavily regulated small business.
