We could probably argue to the end of time about the qualitative quality of life between then and now. In general a metric of consumption and time spent gathering that consumption has gotten better over time.
I don't think a general sentiment matters much here when the important necessitate are out of reach. The hierarchy of needs is outdated, but the inversion of it is very concerning.
We can live without a flat screen TV (which has gotten dirt cheap). We can't live without a decent house. Or worse, while we can live in some 500 sq ft shack we can't truly "live" if there's no other public amenities to gather and socialize without nickel-and-diming us.
Let's kill this myth that people were lounging around before the Industrial Revolution. Serfs for example were working both their own land as well as their lord's land, as well as doing domestic duties in the middle. They really didn't have as much free time as we do today, plus their work was way more backbreaking, literally, than most's cushy sedentary office jobs.
pre-industrial? Lots of tending to the farm, caring for family, and managing slaves I suppose. Had some free time between that to work with your community for bonding or business dealings or whatnot.
Quite the leap to go from "pre-industrial people" to "Antebellum US Southerners", and even then the majority of that (hyperspecific) group did not own slaves.
Edit: There is some research covering work time estimates for different ages.
