I think my underlying thesis probably renders to something like:
The idea that people in the past had personalities that valued the pursuit of perfection more-highly than now is often assumed, but seldom is good evidence given to support it.

Example "humans weren't fundamentally different" hypothesis: When it is more expensive to make multiple attempts, people invest more effort into making sure they do very good attempts, in order to avoid the downside risk. This does not mean they would not have gladly chosen an average-result if dramatically lower production costs were possible. Therefore the difference does not stem from a change in mentality, but from economic factors.

It's kind of like looking at airplanes of the 1950s, with beds and champagne and caviar, and ruefully comparing them to the ones of the 2020s.
Is it because airlines became greedier? Did the average passenger (in the same income-bracket) lose their desire for fine things? Nah: It's probably because once you remember to adjust for inflation, those 1950s passengers were paying $7,300 per flight instead of today's $600.
