Thinking about uniforms. Most schools I attended were run like North Korea.
Inmates wore uniforms. Uniform codes were strictly enforced.
There were many arbitrary rules. Breaking rules resulted in arbitrary detention and in my day beatings, some of which were quite brutal. Prisoners were often kept in solitary confinement.
There was "nationalism", school songs and so on.
We were all indoctrinated with the same useless knowledge designed to make us better citizens.
In my day this included systematic lies about the history of our country and especially the wars of aggression we fought against the Māori in order to steal their land. I believe this has changed to some extent in NZ. Here in the UK, they mostly still seem to believe that the British Empire was a benign force for spreading civilisation.
The leader or headmaster generally had a funny haircut and we had to treat them with exaggerated deference. They held assemblies in which we were forced to listen to interminable speeches which extolled the ideology of the state. [An obvious difference is that we did not have to salute].
The schools were surrounded by fences and no one was permitted to leave.
The staff were frequently paranoid about what inmates got up to and we were constantly under surveillance. Teachers had networks of informants.
I've never been to school in the UK, but looking at the uniforms and the environments, as well as what I can glean from TV, the whole set up is far worse here.
A lot of work places are also like North Korea these days. Democracy has seldom extended to the workplace or school. And they wonder why we don't take it seriously?
