A social experiment
Even outer-space aliens can see the effects of communism.
Also check out North Korea’s creepy Ryugyong Hotel, built at a cost of some 2% of GDP the hotel towers over Pyongyang but it’s a shell that has never been completed because of stuctural problems due to poor quality. The North Koreans have gone so far as to remove it from some maps but there is no hiding the 7th tallest building in the world!
Thanks to Mahalanabois for the picture and Ted Frank for the hotel recommendation.
