The problem with switching to services is, unless they are directly to serving people and physically dependent, either in that it is hardware in an area or a person directly (like a doctor or hair stylist), you are going to have it be something that can be done remotely, opening up the entire world, and driving wages down a LOT in areas. IT industry professionals got devestated by that happening (count me in that area). You can also factor that services jobs can scale. When they scale, you develop pay structures like you see in the entertainment industry and professional sports. At the top someone gets obscenes amount of money, while others at the bottom get paid the minimum... or even do the work for free, because they don't have a choice.
As for anything else, well.... we are at a loss as to what the next breakthrough will be to generate growth. They say Green Jobs, but that is WAY overplayed.
