So you would define an airline pilot as skilled labor but driving an Uber (I have never used Uber, so I will compare it to a taxi) as unskilled labor.
Flying a plain certainly takes a skill. So does driving a car. Both are skills. They certainly differ in the time required to obtain that skill, but that does not change the fact than an unskilled person can't drive a car through dense urban traffic bringing you safely to your destination, neither can they land a an airplane.
If a job was really unskilled, anybody could do it without any training at all. People usually don't pay for actually unskilled things because they can do it themselves just as good
