you might want to read about NK >2023, which is quite different from before, of course there is golf courses, cellphones (with Internet, chats...), TV, money transfer, IT schools, ATMs, money changers for USD, cinemas, american movies, markets (with a ton of illicit products from US/EU/China... i.e you can buy USB sticks with ton of movies or music or ebooks), it's changing gradually, millions are living a relatively peaceful life, but a lot are suffering still especially if they don't have family that can go to major cities to send back money, all those aren't only available in Pyongyang contrary to popular beliefs, there is multiple major cities.

There is a huge amount of money invested currently by the gov into making it a better country, it's hard to believe tho.

It's relatively hard to get information without translating South korean forums because the western news just straight up shit on everything related to NK and almost NEVER show anything progressing over there, which is false.
