I recently saw a mini-documentary about the segmented apartments in Hong Kong, and how because now they’re banned, some of them have been made into mini-museums as a kind of walk-through PSA about the horrific conditions people were forced to live in only 20 years ago. As interesting as things like that and the Kowloon Walled City are from a historical point of view, I’m glad that the government turned it into a park and people have better living conditions now.
Having examples for people to see is essential for making sure people remember what they came from and why they shouldn’t want to go back to it. This is something I think communist countries need to get on more efficiently, museums of capitalism and its historical conditions. This is also very important to capitalism, with its museums to feudalism and (at least here in europe) heavy focus in education on feudal lives).
