Same answer as to Silurian's last remark.

Perhaps it helps to imagine yourself back in 1500
Where does the music play ?
What dreams, objectives, fears do the mighty and the little people have ?
How much was influenced by the little people... how much by the mighty ?
How do they pursue them and change the world in which they live to get them ?
What are your first priorities of life ?

Something about public works spending? Something about non agricultural labor growth?

[Hrothbern]

Something about public works spending?

no

Something about non agricultural labor growth?

that was a result of it

 

[Goodfella]

Crop yields?

 

[Lohrenswald]

that was a result of it

No need to read the whole article.
I posted it to show how important town walls were for late medieval and early modern period people
That map shows something also important in that time

Crop yields?

no
