My only reservation is that the OP fails to mention that some workers died during the construction of The Empire State building: According to the builder, "only" 5 workers died, but according to a newspaper, 14 workers died.[a] No one in the developed world would want to finish a project faster and for less money if the cost has to be measured in human lives -- expect in extreme circumstances, like war.[b]

[b] In some parts of the world, projects are routinely finished faster at the expense of human lives. For example, according to https://www.theguardian.com/football/2022/nov/27/qatar-death... , between 6,500 and 15,000 workers died, and more were injured, to build all the stadiums and facilities in time for the World Cup in Qatar, a tiny country in the Middle East / Western Asia with a total population of under 3M people.

EDITS: Added " -- expect in extreme circumstances, like war" to the last paragraph, and a link to Patrick Collison's fantastic page with examples of "people quickly accomplishing ambitious things together" and thoughts on why projects take so much longer today.
