Have you ever been involved in the process of growing food? A workday on the farm is substantially longer than any office job, the only way to talk to people is to scream because they're at least thirty meters away from you most of the time. At the end of it you're drained and people who have been doing it all their lives get to live the last years of their lives with terrible back pains and having to rely on the young folks for, um, growing food, because it turns out doing manual labour for twelve hours a day isn't so easy when you're eighty. There's anything but quality time in that.

Edit: It also turns out that, with foodstuffs having to be so cheap, this kind of work was also very badly paid, which meant that except for people who owned huge amounts of land (and generally didn't work all, or more commonly any of it), people who had to do this were, if not dirt poor, in any case poor enough not to be able to afford too much. It's the fact that we lost all this chance to have "quality time" that allows us to heartily debate such matters through silicon stuff that shoves charge carriers through really thin glass tubes.
