We each approach this in our own way, from our own perspective. I am not sorting the different perspectives into a hierarchy.
It is true that most 'ordinary people' ( I quibble with that term) had less in order to create and I believe that this was good. In order to create a tribute to God, sacrifice is necessary, regardless of the religion. Even without religion, Kafka's parable about the necessity of the construction of the Great Wall of China comes to mind, as a means of binding all together. Their sacrifice is what elevated them from being ordinary.
The architecture which our civilization will leave behind is brutal enough to make Stalin cringe, and I do not see 'ordinary' people living lives of great dignity. For that matter...three hundred years from now, will anyone marvel at my efforts, as I do when I see the Burgos cathedral?
A more common feeling that I had seeing the cathedrals in Spain was one of sadness.
Moving through the cathedrals and monasteries, I felt that the language of what was involved is now barely intelligible and I could only pick up the vapors of what had been before. In Samos, the monastery there had at one time been a World centre in the field of theology and and philosophy with a famous library. Now it is just a galvanized corpse of what had been before, with perhaps a half dozen monks as groundskeepers. Who knows what undiscovered works lie in its library. In my weaker moments, I feel that the beliefs that created our civilization will soon be as indecipherable as Egyptian hieroglyphs.
Sorry for going down my own rabbit hole. I've had either too many, or not enough, ciders, LOL.
