Essentially, when we get disconnected from 'the simple life', we glorify and idolize it.
Having come from back-woods, subsistence farming to a white-collar, higher education job, I can tell you that (a) very few people understand the amount of stress and work required to survive in subsistence farming, (b) seriously, stress; you can starve, or (c) how much it sucks to do without modern conveniences like computers, internet and electricity.
Ever wonder why current day subsistence farmers aren't well known for their poetry or art? Because they spend all of their time finding and growing food.
In the future, I think we'll see a combination of McJob and responsibility for one's own future, much as we've seen for every generation before. The more things change, the more they stay the same.
