Fascism doesn’t emphasize economics, it’s a minor point in the ideology. Most Fascist governments allowed a private sector to run, but they also nationalized any industry they wanted on a whim. There were also a lot of nonsensical regulations, but as long corporations didn’t question the state then they were fine. North Korea doesn’t really have a private sector or an economy, but again the focus of Fascism is mostly political and social. North Korea functions similarly to other Fascist regimes. North Korea is authoritarian, ultranationalist, ultra militaristic, it’s run by a dictatorial leader, it is centralized autocracy, the government does forcibly suppress opposition, the government does pump out propaganda telling its citizens that subordination of individual interests for the perceived good of the nation is a must, and so on. It’s a Fascist state.
