A title comparing these apartments to prison cells and a picture of an apartment half the size. Seems like this article is trying pretty hard to make dense living look bad.
There are many environmental and psychic benefits to requiring/desiring fewer possessions.
If we want to sustain a growing population, we're going to have to confront the bias the title of this article shows.
Or alternatively, we could just build decent places to live in the vast amounts of empty space owned by a handful of rich people who inherited it (UK bias here; don't know how the upper class landowners got the land in other countries).
