I wonder if 60 minutes looked at South Korea and surely other countries do this too
Though due to small landmass in Korea many of this development are by nature closer to a larger city.
The cities are planned and built on a dirt patch, and it takes 20 years to fill up. Even Seoul could be considered, where whole sections went from few hundred to million population in a space of ten years or so. Ie you can google apartments parks where 200 apartments buildings are built in one large block and a kilometres away another 100 to 300 apartment block is built.
The latest is Sejong City
population 1 in 2012
Polulation 300,000 in 2018
Considered a success and still expanding,
(typically planned cities have patron government departments or large enterprises moving in on opening, some older example else where in Korea is Samsung City near Suwon region 50km from Seoul, and Posco town located 90km etc)
When Sejong city opened there would have been apartments that was not occupied for 5 years as the city wasn’t allowed residents until it opened.
In 2012 official opening there was 15,000 empty apartments.
Songdo Intertantional Business District. Running behind but a beautiful place when I was there last year.
Not very successful due to lofty ambitions and not having a “patron government department or keystone enterprise” but getting there
Population zero 2014 with 80,000 apartments.
Construction continues for more apartments???? Not sure why they don’t delay delay but as more companies relocate, would mean more people and the people like the area very much.
Population in 2018 100,000
It’s a lonely place right now

Sometimes late at time, in certain areas of Songdo it was surreal, like a scene of West World, where all brightly lit super modern buildings on one side and tiny farms from 1950 as you walk down, all of the ground retail store obviously never has a shop in it.
