How Skilled is a Drone Pilot?

The barrier to entry to become a certificated remote pilot and operate professionally has been set terribly low.  Nearly anyone can study a few evenings, pay $150 and pass the Unmanned Aircraft General exam at a testing center.  From that point forward, they possess a certificate that states they qualify to operate a drone for non-recreational purposes in the National Airspace System (NAS).  That’s it.  They are then a pro.  So what helps them create value over others who achieved the same status?
