It's certainly true that in our current society that we need various forms of "jobs" so that work that's required can be done. But it wasn't always this way, and it won't always be.
This society is just a transition, like all others, and one day we'll rise to a new level of contribution and creation that will change the way we live. Right now it works to have large organisations paying people to trade time for money to get things done. Recently though, the shift has gone from paying people for work, towards paying people for value. Honestly though, paying people for thair value is the real way it's always been, it's just been covered up by the salary and the wage of the current times.
I do forsee a lessening of the corporate structure and a breakdown in the way we all do business. I'm not sure what the next step in societal evolution will be, but I hope I'm alive for it.
