It's ignorance, I think.

Typical Moscow 'socialistic' houses were 5- 9- or 16-floors, with some space between them. Depending on density, availability of schools, etc they were more or less livable and very boring.

The photo, in contrast, shows tightly coupled ~30 floor houses. Districts like this could be found in nowadays very capitalistic 'New Moscow' and I call it a recipe for disaster.
