The only thing missing from your analogy is the fact that the shacks were filled with personal diaries and curios, while the skyscrapers are mostly chock-full of homogenous sewage slurry.

Modern overdesigned sites are sort of like modern apartment buildings: shitty build quality under fake plastic marble and wood.
