I mean, to a degree i can understand what you mean. We are seeking happiness in the treadmill and that rarely seems to bring it. We hope that after the treadmill there will be happiness, but few are sure of that.
My problem though, with what i took from your words, was that it sounds like you believe work is becoming less and less required. I don't feel that's true, unfortunately.
I think that will become true, in time, but we don't have the technology to automate the work we need to. Sure, we have various factory line jobs replaces with robotics, and we're working on lots of general replacement (Taxis, for example), but most of the labor force, even "just" manual labor, requires specific intensive understanding that we are not even close to replicating with robotics. Hell, we're still struggling to walk easily and effectively. Sure, walking robots are becoming more natural and skilled, but it's definitely still a WIP.
My robotics leap may have seemed odd, but that's what i believe is required before your comment holds true. Work will always be required - there is no doubt about that. Someone, some thing, will be doing work. And humanity will only be able to ignore work once we've enslaved something else to do it for us.
So back to topic, i think part of the stress you feel from society is a bit of a "i have to do it, so you have to do it" thing. Why should you get to do what you like, when others so clearly cant? You could argue that we're all expecting too much, we don't need the gadgets/etc, and that living very frugal can be a means to happiness, but living frugal doesn't absolve yourself from work.
The frugal lives of the world still work. Some may not work as hard, some may have much more free time, but there's still work to be done. You still have to learn the trades to repair your stuff, or pay someone else to do it for you. To grow your food, or to pay someone else to. And etc.
I'm not trying to come off aggressive, so i hope it doesn't seem that way. Perhaps i'm missing your point, but the statement of:
> ... and it's fine, because work is less and less necessary.
Seems very very foreign to me.
