Comment: Apparently things have not changed much since then ... Check out this youtube video posted in 2015 by WSJ about the 57 story building that was put up in 19 days in China. https://www.youtube.com/watch?v=N6f_sayw0mM With this kind of technology all the slums in India and elsewhere could be resolved very quickly.
