I don't think a vague sense that "they had it better" is necessarily what's at issue. The popular image of the peasant is that they must have spent most of their lives toiling away. What the historical record shows is rather different. I don't think any of us are arguing for regressing society to feudalism (well, besides [your least favorite political figure here] at least, ha ha), but looking at the disparity does give us something to interrogate -- why did we adopt the kind of hours we work now? Do they still make sense? (I think the first question is probably easier to answer than the second)
