> So you clearly agree that some things can be learned by most people who put their mind to it.
Absolutely! I think people can learn almost anything. Barring true disabilities, I believe anyone can learn to program, translate a foreign language, play a violin, play basketball, swim or most other things.
But I don't think most people have even a chance of becoming the best.
What you refer to as "endowed traits" affect everything from our life span to our appearance to our level of happiness, personality traits and ability to learn different skills. They affect every possible kind of skill we could choose to pursue and even what kinds of things we're inclined to pursue.
I also don't agree than the skills needed to succeed as an athlete or musician are "less learnable" than others. On the contrary, I think they're extremely well defined and that we have millennia of collective knowledge in how to train them, thus making them extremely learnable.
The perspective I was coming from is the difference between an economic tournament, where wage differences are based more upon the relative differences of individuals rather than upon their marginal productivity.
This is crucial because while almost anyone can learn to play the piano or to repair a house, very, very few people have even the possibility of being one of the top few people in the world at either. The difference is that people doing the latter are paid based on their marginal productivity and those doing the former are paid based on their approximate ranking among all other pianists in the world and in their city.
As a result, repairing houses is a modest career opportunity open to a large number of people with sufficient absolute skill regardless of their relative ranking in the world. Being a pianist, on the other hand, is a fantastic career for an extremely small number of people at the top and an unsustainable one for nearly everyone else. Some teach on the side and pursue their dreams for years.
The question is, "Is YouTube an economic game where rewards are based primarily on marginal productivity or are they based more on relative comparisons between participants?"
