Your evidence is one poorly-written newspaper article, a reddit disaster-porn post, and some random picture of Caracas?
Authenticity of the reddit post aside, do you have the slightest knowledge of urban development in the Soviet Union, or like, anywhere, or do you just regurgitate links?
A lotta shit got built 'cause you need to house a lot of people after your country's major urban centers got basically raized to the ground, the surrounding countryside along with it, alongside continuing rural->urban migration. Ain't particularly easy to do that well while also trying to recover your economy from a massive fucking brutal invasion.
Yes, Khrushchevkas aren't exactly marvels of architectural longevity; they were never intended to be. They were supposed to last maybe 30-40 years at best, and they're still standing. Sure, they're shoddy and they look like shit now, the countries that built them lacked the capital to replace them as intended--that's another history lesson, but whatever. You mock them for carrying on shambling well past their intended use? They should be lauded for lasting as long as they have, with what limited resources and tight constraints under which they were originally built.
Point is, you want the government to cheap housing and fund it as such, it does so, and the output sometimes ends up surpassing your original goals! You put funding into producing good housing and government can do that too! You ever been to Singapore? You ever hear about the sprawling abject rotten slums of Singapore, that dominate the whole of the nation? No? Curious that.
Would be really fucking strange to hear that a government could build a lot of good housing for its populace and still succeed economically, I suppose, but hey, they did it: https://en.wikipedia.org/wiki/Public_housing_in_Singapore
