And you somehow genuinely feel that the average person's prosperity was, relatively, better in that period?
Working 7 days a week, morning to night, producing that prosperity and trade for the educated class in exchange for a pittance. Whilst eating your table scraps in the dark, you can hope you don't die of a disease you have no idea how to prevent contracting.
You can measure the prosperity of an era by contemporary descriptions of their health, including how tall people were. So we definitely have proof people fared better then.
It feels like it might impact your view a bit if you did.
As good as it is to be marginally taller for 30-40 years, or be a super tall person who died an infant. Not that the article you linked has any description of heights related to whichever "golden age" you might refer to, but whatever.
Pick your golden era and then show me an article that indicates the average height was greater in that period than it is now, if this is the point you really want to focus on.
