There is no freedom of speech.

There is no way for the people to vote out corrupt political officials.

It is a totalitarian form of government. The government intrudes on every aspect of the personal and the nation. This can have negative results if the government makes a series of bad decisions or the people in power are morally corrupt. In other governments, people can live under a corrupt regime with it barely affecting their own social lives and community.

There are no examples of national socialism in peace time that was not in preparation for a war. How does the government organize its youth during peace time? If it is just national boy scouts, I don't see a problem but The Hitler Youth were training boys to want to enlist in the military when they became adults. This is not a great idea because it sends a bad message to other nations that are hostile against yours. If they believe you are going to war with them in the future, they might attack you first with a pre-emptive strike or a self defense war. What face your country puts out to others is important, especially if you want to participate in global trade.
