Even in a hypothetical post-scarcity world, there are things to do, and objectives to pursue. The question is just whether your survival and well-being are dependent on your pursuits. Transitioning the world to a place where one's job is not a major part of one's identity would be a massive, and probably misguided effort.
Also, it's also pretty clear that this guy doesn't understand the graph he has posted here: http://techcrunch.com/2013/01/26/america-has-hit-peak-jobs/
That's a static snapshot. It's not like there is a fixed group that is always in the top 2%. In fact, one would hope in a meritocracy, there is a healthy flow in and out of the 2% that keeps people striving and attempting new things. A world where there's a permanent fixed elite is a world of stagnation.
