To be fair, there are skills that outlive their usefulness over time as technology changes.
Not a lot of blacksmiths around, for example, although you can still find one if you need one.
A lot of people are doing jobs now that didn't exist thirty years ago. That counts for something, too.
There still seem to be plenty of plumbers and electricians, if we're just talking the general ones. I suppose an MBA could do the work, but then he really wouldn't be an MBA any more.
And yes, the digital information network has made it much easier to work with people located around the world. That's going to take time to reach its level, and there really isn't much we can do about it.
