There are 80 percent jobs, but unlikely for highly sought after careers(note career != jobs) with nonlinear payoff functions. Think of the NBA, Olympic athletes, or movie stars. The performance difference between the top 10 people versus unemployed is probably much less than 20 percent. In the extreme case: a 100 m sprinter sprinting 12 seconds vs 10 seconds is the difference between gold vs unknown.
It's nice that you address an unrepresentative teeny tiny micro sliver of the employed, but is there anything you can add for the majority?
