It's almost comical the different ways that North Korea tries to make money. Kim Jong Un is almost like a comic supervillain with his own country.

Among other things, they engage in:

* Manufacturing methamphetamine https://www.talkingdrugs.org/north-korea-increasing-crystal-...

* Fake money https://news.vice.com/article/north-koreas-counterfeit-benja...

* Counterfeit cigarettes and pharmaceuticals

* People trafficking

* A restaurant chain: https://en.wikipedia.org/wiki/Pyongyang_(restaurant_chain)

* Statues for African dictators: http://www.bbc.com/news/magazine-35569277

Their embassies are also expected to make a profit and sustain themselves, while sending money home.

The North Korean Embassy in Pakistan was suspected to be bootlegging alcohol: https://www.reuters.com/article/us-pakistan-northkorea-insig...

They rent out embassy owned land for a youth hostel in Berlin: https://www.washingtonpost.com/news/worldviews/wp/2017/10/05...

They also smuggle ivory in Africa: https://www.economist.com/news/middle-east-and-africa/217295...

It's almost comical. The North Korean regime is completely morally bankrupt.
