Historically, cathedrals might stand unfinished for decades at a time. Also the early days railroads were famous for brutally exploiting labor in order to get built as soon as possible. Haven't you heard of John Henry?

I haven't heard of him. I did not understand you. It seems you believe there isn't collaboration to build cathedrals, railroads, and feature-length films.

Of course not. What I'm saying is that these are very much not examples of well-run projects that aren't exploitative of labor.
