There's a kind of twisted logic to it. If your construction techniques are constantly improving and the high volume of construction incentivizes you to develop more cost efficient construction technologies, then planned obsolescence of buildings is like planned obsolescence of phones. Build soviet block apartments, knock down in 20 years, replace with prefab building compartments with wiring and plumbing built in at the factory. Then export the prefab technology worldwide to take advantage of the infrastructure boom in other developing countries. Isn't build fast, break fast, and learn fast the whole silicon valley ethos?
