Seems like there has to be a balance between job availability and manufacturing output. If people don't have jobs, they can't afford to buy the robot produced goods. Manufacturers can produce cheaper goods using robots, but they have to have people to buy them, otherwise the technology isn't going to do them much good.
That's just a thought. If a balance of some sort needs to be there, it will probably happen. If it doesn't need to be there, I guess we would be looking at a different paradigm.
