> was enough for a single person to feed a family and have some extra using manual labor. No, that was ten serfs each working 30 hours a week to in aggregate grow enough food to subsist on and generate the master's demanded surplus. That was also only true in good years. In bad years a portion of serfs just died. A serf's life sucked in every dimension. Even if they only "worked" 30 hours they spent the rest of their time in squalor. If you think working in a field is so attractive there's lots of farms looking for day labor. Try it out.
