>we had no problem building houses for people in the 50s and 60s. Why all the sudden we can't do it in the last 20 years?
Yea, it's actually pretty easy. Just get in a time machine and go back to 1956 when the Federal Highway Act made all that development possible, and just tell them to build sixteen-lane highways through every major city instead of two-lane highways. Explain that in 70 years, those highways will be operating overcapacity, so that a commute in and out of the city will not be able to operate at optimal speed of a vehicle, so that traveling 30 miles will not take 30 minutes, rather it will often take 60 minutes or longer, thus making central real estate more valuable. Which, in turn, creates a feedback loop that makes the viable transportation range of the urban center smaller and smaller. And, thus, makes the real estate in that smaller area more and more valuable. However, if you can get those highways doubled or tripled in size it should stop that feedback loop for now.
Once you convince them to do that, feel free to come back to 2024, and all our development concerns will go away for another 70 years, at which point, someone will have to get in the time machine to make it 38 lane highways.
