I'm not sure that I am rebutting a different argument. When you said that hunter/gathers generally have more leisure time I interpreted that as meaning "more than us". Which is exactly what I was disagreeing with.
I don't spend 8 hours a day performing an activity that pays for my food and shelter: my wage is 3x my basic needs. So it takes me about 2.5hrs of work to do that. I do actually have a flexible work environment where I could stop at that point, but instead I stick around for another 5hrs and take home more cash. That is not an excess as you have phrased it - I can operate in other markets than basic needs and I am procuring funds for those.
Also, I did not imply that you had claimed that hunter gatherers have it easy, although you may have been misled by my british turn of phrase. I would claim that 13-20hrs of work a week is having it easy, my question to you was whether or not that was true that hunter/gathers worked less than this? My assumption is that they would need more time than this to acquire food each week.
