Who belongs in a city?  (transcript)
Summary
I understood that there is less number of big buildings in Japan relatively. It's because it's difficult to forcibly let people move a land they live. It's expensive because people deeply attach their land. Even country or government use their land to use it a lot of citizens usefully, amount of money is needed. Then some people who lend or sold it are rich. However, there are people who don't want to sell their land. There, buildings aren't built and streets are bent. I think that it's beyond guarantee and it'll be a curse of the land.
There is not cooperation there.
This story also doesn't have cooperation between government and citizens. I thought that in the poor city, to build a lot of buildings could help people because they work there. However, the poor is just eliminated.
For creating big cities, some people’s lives shouldn't be destroyed.
